56800E 56F8xxx Microcontroller IC 16-Bit 60MHz 128KB (64K x 16) FLASH 128-LQFP (14x20)

Device Description

The 56F8345 and 56F8145 are members of the 56800E core-based family of controllers. Each combines,

on a single chip, the processing power of a Digital Signal Processor (DSP) and the functionality of a

microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because

of their low cost, configuration flexibility, and compact program code, the 56F8345 and 56F8145 are

well-suited for many applications. The devices include many peripherals that are especially useful for

motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and

control, automotive control (56F8345 only), engine management, noise suppression, remote utility

metering, industrial control for power, lighting, and automation applications.

The 56800E core is based on a Harvard-style architecture consisting of three execution units operating in

parallel, allowing as many as six operations per instruction cycle. The MCU-style programming model and

optimized instruction set allow straightforward generation of efficient, compact DSP and control code.

The instruction set is also highly efficient for C/C++ Compilers to enable rapid development of optimized

control applications.

The 56F8345 and 56F8145 support program execution from internal memories. Two data operands can be

accessed from the on-chip data RAM per instruction cycle. These devices also provide two external

dedicated interrupt lines and up to 49 General Purpose Input/Output (GPIO) lines, depending on peripheral

configuration.

56F8345 Features

The 56F8345 controller includes 128KB of Program Flash and 8KB of Data Flash (each programmable

through the JTAG port) with 4KB of Program RAM and 8KB of Data RAM. A total of 8KB of Boot Flash

is incorporated for easy customer inclusion of field-programmable software routines that can be used to

program the main Program and Data Flash memory areas. Both Program and Data Flash memories can be

independently bulk erased or erased in pages. Program Flash page erase size is 1KB. Boot and Data Flash

page erase size is 512 bytes. The Boot Flash memory can also be either bulk or page erased.

A key application-specific feature of the 56F8345 is the inclusion of two Pulse Width Modulator (PWM)

modules. These modules each incorporate three complementary, individually programmable PWM signal

output pairs (each module is also capable of supporting six independent PWM functions, for a total of 12

PWM outputs) to enhance motor control functionality. Complementary operation permits programmable

dead time insertion, distortion correction via current sensing by software, and separate top and bottom

output polarity control. The up-counter value is programmable to support a continuously variable PWM

frequency. Edge-aligned and center-aligned synchronous pulse width control (0% to 100% modulation) is

supported. The device is capable of controlling most motor types: ACIM (AC Induction Motors); both

BDC and BLDC (Brush and Brushless DC motors); SRM and VRM (Switched and Variable Reluctance

Motors); and stepper motors. The PWMs incorporate fault protection and cycle-by-cycle current limiting

with sufficient output drive capability to directly drive standard optoisolators. A “smoke-inhibit”,

write-once protection feature for key parameters is also included. A patented PWM waveform distortion

correction circuit is also provided. Each PWM is double-buffered and includes interrupt controls to permit

integral reload rates to be programmable from 1 to 16. The PWM modules provide reference outputs to

synchronize the Analog-to-Digital Converters through two channels of Quad Timer C.

The 56F8345 incorporates two Quadrature Decoders capable of capturing all four transitions on the

two-phase inputs, permitting generation of a number proportional to actual position. Speed computation

capabilities accommodate both fast- and slow-moving shafts. An integrated watchdog timer in the

Quadrature Decoder can be programmed with a time-out value to alert when no shaft motion is detected.

Each input is filtered to ensure only true transitions are recorded.

This controller also provides a full set of standard programmable peripherals that include two Serial

Communications Interfaces (SCIs); two Serial Peripheral Interfaces (SPIs); and four Quad Timers. Any of

these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function is not required. A

Flex Controller Area Network (FlexCAN) interface (CAN Version 2.0 B-compliant) and an internal

interrupt controller are also a part of the 56F8345.

Introduction

The MC9S12G-Family is an optimized, automotive, 16-bit microcontroller product line focused on

low-cost, high-performance, and low pin-count. This family is intended to bridge between high-end 8-bit

microcontrollers and high-performance 16-bit microcontrollers, such as the MC9S12XS-Family. The

MC9S12G-Family is targeted at generic automotive applications requiring CAN or LIN/J2602

communication. Typical examples of these applications include body controllers, occupant detection, door

modules, seat controllers, RKE receivers, smart actuators, lighting modules, and smart junction boxes.

The MC9S12G-Family uses many of the same features found on the MC9S12XS- and MC9S12P-Family,

including error correction code (ECC) on flash memory, a fast analog-to-digital converter (ADC) and a

frequency modulated phase locked loop (IPLL) that improves the EMC performance. 

The MC9S12G-Family is optimized for lower program memory sizes down to 16k. In order to simplify

customer use it features an EEPROM with a small 4 bytes erase sector size.

The MC9S12G-Family deliver all the advantages and efficiencies of a 16-bit MCU while retaining the low

cost, power consumption, EMC, and code-size efficiency advantages currently enjoyed by users of NXP’s

existing 8-bit and 16-bit MCU families. Like the MC9S12XS-Family, the MC9S12G-Family run 16-bit

wide accesses without wait states for all peripherals and memories. The MC9S12G-Family is available in

100-pin LQFP, 64-pin LQFP, 48-pin LQFP/QFN, 32-pin LQFP and 20-pin TSSOP package options and

aims to maximize the amount of functionality especially for the lower pin count packages. In addition to

the I/O ports available in each module, further I/O ports are available with interrupt capability allowing

wake-up from stop or wait modes.
