HCS12X HCS12X Microcontroller IC 16-Bit 80MHz 512KB (512K x 8) FLASH 144-LQFP (20x20)

Introduction

The MC9S12XD family will retain the low cost, power consumption, EMC and code-size efficiency

advantages currently enjoyed by users of Freescale's existing 16-Bit MC9S12 MCU Family.

Based around an enhanced S12 core, the MC9S12XD family will deliver 2 to 5 times the performance of

a 25-MHz S12 whilst retaining a high degree of pin and code compatibility with the S12.

The MC9S12XD family introduces the performance boosting XGATE module. Using enhanced DMA

functionality, this parallel processing module offloads the CPU by providing high-speed data processing

and transfer between peripheral modules, RAM, Flash EEPROM and I/O ports. Providing up to 80 MIPS

of performance additional to the CPU, the XGATE can access all peripherals, Flash EEPROM and the

RAM block.

The MC9S12XD family is composed of standard on-chip peripherals including up to 512 Kbytes of Flash

EEPROM, 32 Kbytes of RAM, 4 Kbytes of EEPROM, six asynchronous serial communications interfaces

(SCI), three serial peripheral interfaces (SPI), an 8-channel IC/OC enhanced capture timer, an 8-channel,

10-bit analog-to-digital converter, a 16-channel, 10-bit analog-to-digital converter, an 8-channel

pulse-width modulator (PWM), five CAN 2.0 A, B software compatible modules (MSCAN12), two

inter-IC bus blocks, and a periodic interrupt timer. The MC9S12XD family has full 16-bit data paths

throughout.

The non-multiplexed expanded bus interface available on the 144-pin versions allows an easy interface to

external memories

The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit

operational requirements. System power consumption can be further improved with the new “fast exit from

stop mode” feature.

In addition to the I/O ports available in each module, up to 25 further I/O ports are available with interrupt

capability allowing wake-up from stop or wait mode.

Family members in 144-pin LQFP will be available with external bus interface and parts in 112-pin LQFP

or 80-pin QFP package without external bus interface. See Appendix E Derivative Differencesfor package

options.

Introduction

The new MC9S12XE Family of microcontrollers takes the innovation of today’s MC9S12XD Family a step further with

the introduction of new features to deliver enhanced system integrity and greater functionality. These new features include

a Memory Protection Unit (MPU) and Error Correction Code (ECC) on the Flash memory together with enhanced

EEPROM functionality (EEE), an enhanced XGATE, a Frequency Modulated Phase Locked Loop (IPLL) and a faster

ATD. The E Family will extend the S12X product range up to 1MB of Flash memory with increased I/O capability in the

208-pin version of the flagship MC9S12XEP100.

Targeted at automotive multiplexing and generic auto body applications, S12XE Family will deliver 32-bit performance

with all the advantages and efficiencies of a 16-bit MCU. It will retain the low cost, power consumption, EMC and codesize

efficiency advantages currently enjoyed by users of Freescale’s existing 16-bit S12 and S12X MCU families.

There is a high level of compatibility between the S12XE and S12XD families.

Like members of other S12X families, the S12XE Family will run 16-bit wide accesses without wait states for all peripherals

and memories.

The S12XE Family features an enhanced version of the performance-boosting XGATE co-processor which is

programmable in “C” language and runs at twice the bus frequency of the S12X with an instruction set optimized for

data movement, logic and bit manipulation instructions and which can service any peripheral module on the device. The new

enhanced version has improved interrupt handling capability and is fully compatible with existing XGATE module.

As with the S12XD Family, the S12XE Family features an enhanced MSCAN module which, when used in conjunction with

XGATE, delivers FULL CAN performance with virtually unlimited number of mailboxes and retains backwards

compatibility with the MSCAN module featured on existing S12 products.

The S12XE Family has full 16-bit data paths throughout. The non-multiplexed expanded bus interface available on the 144-

pin versions allows an easy interface to external memories. In addition to the I/O ports available in each module, up to 25

further I/O ports are available with interrupt capability allowing wake-up from STOP orWAIT mode. The S12XE Family is

available in 208-Pin MAPBGA, 144-pin LQFP (both with optional external bus), 112-pin LQFP or 80-Pin QFP options.
