All references to the MC68H(R)C908JL3E in this data book apply
equally to the MC68H(R)C908JK3E and MC68H(R)C908JK1E, unless
otherwise stated.
Features of the MC68H(R)C908JL3E include the following:
• EMC enhanced version of MC68H(R)C908JL3/JK3/JK1
• 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 5V operating voltage
– 4-MHz at 3V operating voltage
• Oscillator options:
– Crystal oscillator for MC68HC908JL3E/JK3E/JK1E
– RC oscillator for MC68HRC908JL3E/JK3E/JK1E
• User program FLASH memory with security¹ feature
– 4,096 bytes for MC68H(R)C908JL3E/JK3E
– 1,536 bytes for MC68H(R)C908JK1E
• 128 bytes of on-chip RAM
• 2-channel, 16-bit timer interface module (TIM)
• 12-channel, 8-bit analog-to-digital converter (ADC)
• 23 general purpose I/O ports for MC68H(R)C908JL3E:
– 7 keyboard interrupt with internal pull-up
(6 keyboard interrupt for MC68HC908JL3E)
– 10 LED drivers (sink)
– 2 × 25mA open-drain I/O with pull-up
1. No security feature is absolutely secure. However, Motorola’s strategy is to make reading or
copying the FLASH difficult for unauthorized users.
