MC68HC908JL16

• High-performance M68HC08 architecture
• Fully upward-compatible object code with M6805, M146805, and M68HC05 Families
• Low-power design; fully static with stop and wait modes
• Maximum internal bus frequency:
8-MHz at 5-V operating voltage
4-MHz at 3-V operating voltage
• Oscillator options:
Crystal or resonator
RC oscillator
• 16,384 bytes user program FLASH memory with security(1)
• 512 bytes of on-chip random-access memory (RAM)
• Two 16-bit, 2-channel timer interface modules (TIM1 and TIM2) with selectable input capture, output compare, and pulse-width modulation (PWM) capability on each channel; external clock input option on TIM2
• 13-channel, 10-bit analog-to-digital converter with internal bandgap reference channel (ADC10)
• Serial communications interface module (SCI)
