HCS12 HCS12 Microcontroller IC 16-Bit 25MHz 512KB (512K x 8) FLASH 112-LQFP (20x20)

Overview

The MC9S12DP512 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip

peripherals including a 16-bit central processing unit (HCS12 CPU), 512K bytes of Flash EEPROM, 14K

bytes of RAM, 4K bytes of EEPROM, two asynchronous serial communications interfaces (SCI), three

serial peripheral interfaces (SPI), an 8-channel IC/OC enhanced capture timer, two 8-channel, 10-bit

analog-to-digital converters (ADC), an 8-channel pulse-width modulator (PWM), a digital Byte Data Link

Controller (BDLC), 29 discrete digital I/O channels (Port A, Port B, Port K and Port E), 20 discrete digital

I/O lines with interrupt and wake up capability, five CAN 2.0 A, B software compatible modules

(MSCAN12), and an Inter-IC Bus. The MC9S12DP512 has full 16-bit data paths throughout. However,

the external bus can operate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for

lower cost systems. The inclusion of a PLL circuit allows power consumption and performance to be

adjusted to suit operational requirements.

56800E 56F8xxx Microcontroller IC 16-Bit 32MHz 32KB (16K x 16) FLASH 44-LQFP (10x10)

56F8033/56F8023 Description

The 56F8033/56F8023 is a member of the 56800E core-based family of Digital Signal Controllers

(DSCs). It combines, on a single chip, the processing power of a DSP and the functionality of a

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

of its low cost, configuration flexibility, and compact program code, the 56F8033/56F8023 is well-suited

for many applications. The 56F8033/56F8023 includes many peripherals that are especially useful for

industrial control, motion control, home appliances, general-purpose inverters, smart sensors, fire and

security systems, switched-mode power supply, power management, and medical monitoring

applications.

The 56800E core is based on a dual 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 compilers to enable rapid

development of optimized control applications.

The 56F8033/56F8023 supports program execution from internal memories. Two data operands can be

accessed from the on-chip data RAM per instruction cycle. The 56F8033/56F8023 also offers up to 26

General-Purpose Input/Output (GPIO) lines, depending on peripheral configuration.

The 56F8033 Digital Signal Controller includes 64KB of Program Flash and 8KB of Unified

Data/Program RAM. The 56F8023 Digital Signal Controller includes 32KB of Program Flash and 4KB of

Unified Data/Program RAM. Program Flash memory can be independently bulk erased or erased in pages.

Program Flash page erase size is 512 Bytes (256 Words).
