Features of the MC68HC908JB16 MCU 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
• 6-MHz internal bus frequency
• 16,384 bytes of on-chip FLASH memory with security¹ feature
• 384 bytes of on-chip random access memory (RAM)
• Up to 21 general-purpose input/output (I/O) pins, including:
– 15 shared-function I/O pins
– 8-bit keyboard interrupt port
– 10mA high current drive for PS/2 connection on 2 pins
(with USB module disabled)
– 1 dedicated I/O pin, with 25mA direct drive for infrared LED
(32-pin package)
– 6 dedicated I/O pins, with 25mA direct drive for infrared LED
on 2 pins and 10mA direct drive for normal LED on 4 pins
(28-pin package)
• Two 16-bit, 2-channel timer interface modules (TIM1 and TIM2)
with selectable input capture, output compare, PWM capability on
each channel, and external clock input option (TCLK)
• Universal Serial Bus specification 2.0 low-speed functions:
– 1.5Mbps data rate
– On-chip 3.3V regulator
– Endpoint 0 with 8-byte transmit buffer and 8-byte receive buffer
– Endpoint 1 with 8-byte transmit buffer
– Endpoint 2 with 8-byte transmit buffer and 8-byte receive buffer
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or
copying the FLASH difficult for unauthorized users.
