Freescale Semiconductor, Inc...
The 68HC908AP64/AP32 is a fully integrated
microcontroller created to make system
design easier by eliminating external
peripherals wherever possible. The 32 KHz
phase-locked loop (PLL) virtually eliminates
the need for expensive, high-speed crystals
or noisy oscillators. The integrated
second-generation Flash memory programs
up to 100 times faster than previous Flash
solutions and offers in-application
programming. Features include a
synchronous serial peripheral interface (SPI),
two asynchronous serial communications
interfaces (SCI) (with an infrared
modulator/demodulator on one SCI), a
multi-master inter-IC (I2C) bus, a 10-bit
analog-to-digital converter (ADC), low-voltage
inhibit (LVI) and a watchdog timer.
10-BIT ANALOG-TO-DIGITAL CONVERTER
鈥?Eight channels
鈥?Single conversion in 8.5 碌s
鈥?Fast, easy conversion from analog
inputs鈥攕uch as temperature, pressure
and fluid levels鈥攖o digital values for
CPU processing
CLOCK GENERATION MODULE WITH PLL
鈥?Programmable clock frequency in integer
multiples of external crystal reference
鈥?Crystal reference of 32 KHz to 100 KHz
鈥?External clock option with or without PLL
鈥?RC clock option without PLL
鈥?Provides high performance using
cost-effective, low-frequency
reference crystals
鈥?Reduces generated noise while still
providing high performance (up to 32 MHz)
