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:
Software selectable bus frequencies
25 percent accuracy with a trimming capability of better than 1 percent
Clock monitor
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
