General Description
1.1 Introduction
The MC68HC908EY16 is a member of the low-cost, high-performance M68HC08 Family of 8-bit
microcontroller units (MCUs). 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.
The information contained in this document pertains to the MC68HC908EY8 with the exceptions noted in
Appendix A MC68HC908EY8.
1.2 Features
For convenience, features have been organized to reflect:
⢠Standard features of the MC68HC908EY16
⢠Features of the CPU08
Standard features of the MC68HC908EY16 include:
⢠High-performance M68HC08 architecture optimized for C-compilers
⢠Fully upward-compatible object code with M6805, M146805, and M68HC05 Families
⢠8-MHz internal bus frequency at 5V
⢠Internal oscillator requiring no external components:
â Software selectable bus frequencies
â 25 percent accuracy with a trimming capability of better than 1 percent
â Clock monitor
â Option to allow use of external clock source or external crystal/ceramic resonator
⢠15,872 bytes of on-chip FLASH memory with in-circuit programming
⢠FLASH program memory security(1)
⢠512 bytes of on-chip random-access memory (RAM)
⢠Low voltage inhibit (LVI) module
⢠Internal clock generator module (ICG)
⢠Two 16-bit, 2-channel timer (TIMA and TIMB) interface modules with selectable input capture,
output compare, and pulse-width modulation (PWM) capability on each channel
⢠8-channel, 10-bit successive approximation analog-to-digital converter (ADC)
⢠Enhanced serial communications interface module (ESCI) for local interconnect network (LIN)
connectivity
⢠Serial peripheral interface (SPI)
1. No security feature is absolutely secure. However, Freescaleâs strategy is to make reading or copying the FLASH difficult for
unauthorized users.
