Features of the MC68H(R)C08JL3 include the following:
• 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
• 5V and 3V operating voltages
• 8MHz internal bus operation
• RC-oscillator circuit or crystal-oscillator options
• ROM security¹
• User read-only memory (ROM)
– 4096 bytes for MC68H(R)C08JL3/JK3
– 1536 bytes for MC68H(R)C08JK1
• 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)C08JL3:
– 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)C08JK3/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 ROM difficult for unauthorized users.
