1.1

Introduction

The MC9S12XE-Family of micro controllers is a further development of the S12XD-Family including

new features for 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, an Internally ﬁltered, frequency

modulated Phase Locked Loop (IPLL) and an enhanced ATD. The E-Family extends the S12X product

range up to 1MB of Flash memory with increased I/O capability in the 208-pin version of the ﬂagship

MC9S12XE100.

The MC9S12XE-Family delivers 32-bit performance with all the advantages and efﬁciencies of a 16 bit

MCU. It retains the low cost, power consumption, EMC and code-size efﬁciency advantages currently

enjoyed by users of Freescale’s existing 16-Bit MC9S12 and S12X MCU families. There is a high level of

compatibility between the S12XE and S12XD families.

The MC9S12XE-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 the existing XGATE module.

The MC9S12XE-Family is composed of standard on-chip peripherals including up to 64Kbytes of RAM,

eight asynchronous serial communications interfaces (SCI), three serial peripheral interfaces (SPI), an

8-channel IC/OC enhanced capture timer (ECT), two 16-channel, 12-bit analog-to-digital converters, an

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

two inter-IC bus blocks (IIC), an 8-channel 24-bit periodic interrupt timer (PIT) and an 8-channel 16-bit

standard timer module (TIM).

The MC9S12XE-Family uses 16-bit wide accesses without wait states for all peripherals and memories.

The non-multiplexed expanded bus interface available on the 144/208-Pin versions allows an easy

interface to external memories.

In addition to the I/O ports available in each module, up to 26 further I/O ports are available with interrupt

capability allowing Wake-Up from STOP or WAIT modes. The MC9S12XE-Family is available in

208-Pin MAPBGA, 144-Pin LQFP, 112-Pin LQFP or 80-Pin QFP options.
