MOTOROLA
Data Sheet — MC68HC908QF4
The MC68HC908QF4 MCU is a member of the low-cost, high-performance
M68HC08 Family of 8-bit microcontroller units (MCUs). Optimized for low-power
operation and available in a small 32-pin low-profile quad flat pack (LQFP), this
MCU is well suited for remote keyless entry (RKE) transmitter designs, tire
pressure monitoring (TPM), or other remote sensing and wireless RF data
transmission applications.
All MCUs in the M68HC908 Family use the enhanced M68HC08 central processor
unit (CPU08) and are available with a variety of modules, memory sizes and types,
and package types.
Features of the MC68HC908QF4 MCU include:
1. The oscillator frequency is guaranteed to ±5% over temperature and voltage range after trimming.
2. No security feature is absolutely secure. However, Motorola’s strategy is to make reading or
copying the FLASH difficult for unauthorized users.
