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:
â 15 shared-function I/O pins
â 8-bit keyboard interrupt port
â 10mA high current drive for PS/2 connection on 2 pins
(with USB module disabled)
â 1 dedicated I/O pin, with 25mA direct drive for infrared LED
(32-pin package)
â 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:
â 1.5Mbps data rate
â On-chip 3.3V regulator
â Endpoint 0 with 8-byte transmit buffer and 8-byte receive buffer
â Endpoint 1 with 8-byte transmit buffer
â Endpoint 2 with 8-byte transmit buffer and 8-byte receive buffer
1. No security feature is absolutely secure. However, Freescaleâs strategy is to make reading or
copying the FLASH difficult for unauthorized users.
