Introduction

Targeted at automotive multiplexing applications, the MC9S12XD Family will deliver 32-bit performance with all the advantages and efficiencies of a 16-bit MCU. The S12X is designed to retain the low cost, low power consumption, excellent EMC performance and code-size efficiency advantages enjoyed by users of Freescale’s previous 16-bit MC9S12 MCU family.

Based around an enhanced S12 core, the MC9S12XD Family will deliver two to five times the performance of a 25 MHz S12 whilst retaining a high degree of pin and code compatibility with the original S12D – family.

The MC9S12XD Family features the performance boosting XGATE co-processor. The XGATE, which is programmable in “C” language, has an instruction set which is optimized for data movement, logic and bit manipulation instructions. It runs at twice the bus frequency of the S12X and off-loads the CPU by providing high speed data transfer (and data processing) between any peripheral module, RAM and I/O ports before Break IC. This is particularly useful in applications such as automotive gateways where there are multiple busses carrying heavy data traffic which would otherwise exert a heavy interrupt/processing load on the CPU.

The MC9S12XD Family will feature an enhanced MSCAN module which, when used in conjunction with XGATE, delivers FullCAN performance with virtually unlimited number of mailboxes and retains backwards compatibility with the MSCAN module featured on previous S12 products.

Memory options will range from 64 Kbytes to 512 Kbytes of Freescale’s industry-leading, full automotive spec SG-Flash with additional integrated EEPROM.

In addition to the rich S12 peripheral set, the MC9S12XD Family will feature more RAM, extra A/D channels, new timer features and additional LIN-compatible SCI ports compared with the original S12 D Family. The MC9S12XD Family also features a new flexible interrupt handler which allows multilevel nested interrupts.

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 is further improved with the new “fast exit from STOP mode” feature and an ultra low power wakeup timer.

In addition to the I/O ports available in each module, up to 25 further I/O ports are available with interrupt capability allowing wakeup from STOP or WAIT mode.

The MC9S12XD Family will be available in 144-pin LQFP (with optional external bus), 112-pin, and 80-pin options.

The calibrated internal RC Oscillator provides a fixed 8.0 MHz clock. The frequency is nominal value at 3V and 25°C. If 8 MHz frequency exceeds the specification of the device (depends on VCC), the CKDIV8 Fuse must be programmed in order to divide the internal frequency by 8 during start-up to facilitate Break IC ATmega169P Code.

Break IC ATmega169P Code

The device is shipped with the CKDIV8 Fuse programmed. See “System Clock Prescaler” on page 29. for more details. This clock may be selected as the system clock by programming the CKSEL Fuses as shown in Table 8. If selected, it will operate with no external components. During reset, hardware loads the calibration byte into the OSCCAL Register and thereby automatically calibrates the RC Oscillator.

At 3V and 25°C, this calibration gives a frequency within ± 10% of the nominal frequency. Using calibration methods as described in application notes available at www.atmel.com/avr it is possible to achieve ± 2% accuracy at any given VCC and Temperature. When this Oscillator is used as the IC clock, the Watchdog Oscillator will still be used for the Watchdog Timer and for the Reset Time-out.

For more information on the pre-programmed calibration value, see the section “Calibration Byte” on page 269. When this Oscillator is selected, start-up times are determined by the SUT Fuses as shown in Table 9. Selecting internal RC Oscillator allows the XTAL1/TOSC1 and XTAL2/TOSC2 pins to be used as timer oscillator pins.

Writing the calibration byte to this address will trim the internal Oscillator to remove process variations from the Oscillator frequency. This is done automatically during IC Reset. When OSCCAL is zero, the lowest available frequency is chosen in the process of Break IC ATmega169P Code. Writing nonzero values to this register will increase the frequency of the internal Oscillator.

Writing 0x7F to the register gives the highest available frequency. The calibrated Oscillator is used to time EEPROM and Flash access. If EEPROM or Flash is written, do not calibrate to more than 10% above the nominal frequency. Otherwise, the EEPROM or Flash write may fail. Note that the Oscillator is intended for calibration to 8.0 MHz. Tuning to other values is not guaranteed, as indicated in Table 10.

When applying an external clock, it is required to avoid sudden changes in the applied clock frequency to ensure stable operation of the MCU. A variation in frequency of more than 2% from one clock cycle to the next can lead to unpredictable behavior. It is required to ensure that the MCU is kept in Reset during such changes in the clock frequency.

Note that the System Clock Prescaler can be used to implement run-time changes of the internal clock frequency while still ensuring stable operation. Refer to “System Clock Prescaler” on page 29 for details. When the CKOUT Fuse is programmed, the system Clock will be output on CLKO. This mode is suitable when IC clock is used to drive other circuits on the system.

The clock will be output also during reset and the normal operation of I/O pin will be overridden when the fuse is programmed. Any clock source, including internal RC Oscillator, can be selected when CLKO serves as clock output. If the System Clock Prescaler is used, it is the divided system clock that is output when the CKOUT Fuse is programmed.
