NXP | MC9S12A64CFUE

The MC9S12A128 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit (CPU12), 128 Kbytes of Flash EEPROM, 4 Kbytes of RAM, 1 Kbytes of EEPROM.

The MC9S12A128 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. In addition to the I/O ports available in each module, up to 22 I/O ports are available with Wake-Up capability from STOP or WAIT mode.

The MC9S12A128 has two asynchronous serial communications interfaces (SCI), serial peripheral interface (SPI), an input capture/output compare timer (TIM), 16- channel, 10-bit analog-to-digital converter (ADC), an 8-channel pulse-width modulator (PWM), one CAN 2.0 A, B software compatible module (MSCAN12) and an Inter-IC Bus.
