MC68HC912BL16
Technical Summary
16-Bit Microcontroller
1 Introduction
The MC68HC912BL16 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip pe-
ripherals including a 16-bit central processing unit (CPU12), 16-Kbyte flash EEPROM, 512-byte RAM,
512-byte EEPROM, an asynchronous serial communications interface (SCI), a serial peripheral inter-
face (SPI), an 7-channel timer and 16-bit pulse accumulator, an 10-bit analog-to-digital converter
(ADC), and a four-channel pulse-width modulator (PWM). System resource mapping, clock generation,
interrupt control and bus interfacing are managed by the Lite integration module (LIM). The
MC68HC912BL16 has full 16-bit data paths throughout, however, the multiplexed external bus can op-
erate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for lower cost systems.
