– 1536 bytes for MC68H(R)C908JK1
• 128 bytes of on-chip random-access memory (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)C908JL3:
– 7 keyboard interrupt with internal pull-up
– 10 LED drivers
– 2 × 25mA open-drain I/O with pull-up
– 2 ICAP/OCAP/PWM
• 15 general purpose I/O ports for MC68H(R)C908JK3/JK1:
– 1 keyboard interrupt with internal pull-up
(with RC oscillator option selected)
– 4 LED drivers
– 2 × 25mA open-drain I/O with pull-up
– 2 ICAP/OCAP/PWM
1. No security feature is absolutely secure. However, Motorola’s strategy is to make reading or
copying the FLASH difficult for unauthorized users.
