The MC68HC908AB32 is a member of the low-cost, high-performance
M68HC08 Family of 8-bit microcontroller units (MCUs) with embedded
EEPROM for user data storage. All MCUs in the family use the
enhanced M68HC08 central processor unit (CPU08) and are available
with a variety of modules, memory sizes and types, and package types.
Features of the MC68HC908AB32 include the following:
•
High-performance M68HC08 architecture
•
Fully upward-compatible object code with M6805, M146805, and
M68HC05 Families
•
Memory map and pin functions compatible with MC68HC08AB32
and MC68HC08AB16
•
8-MHz internal bus frequency
•
32K-bytes user program FLASH memory with security
•
512 bytes of on-chip EEPROM with security feature
•
1K-byte of on-chip RAM
•
Clock generator module (CGM)
•
Two 16-bit, 4-channel timer interface modules (TIMA and TIMB)
with selectable input capture, output compare, and PWM
capability on each channel
•
Programmable interrupt timer (PIT)
•
Serial peripheral interface module (SPI)
•
Serial communications interface module (SCI)
•
8-channel. 8-bit analog-to-digital converter (ADC)
•
Low-power design (fully static with STOP and WAIT modes)
•
Master reset pin and power-on reset
1. No security feature is absolutely secure. However, Motorola's strategy is to make reading or
copying the FLASH difficult for unauthorized users.
