ADC
— 8-channel, 10-bit analog-to-digital
converter with automatic compare function
SCI
— Two serial communications interface
modules with optional 13-bit break
SPI
— Serial peripheral interface module
IIC
— Inter-integrated circuit bus module to
operate at up to 100 kbps with maximum bus
loading; capable of higher baud rates with
reduced loading
Timers
— Three
1
16-bit timer/pulse-width
modulator (TPM) modules — Two
1
2-channel
and one 4-channel; each has selectable input
capture, output compare, and edge-aligned
PWM capability on each channel. Each timer
module may be configured for buffered,
centered PWM (CPWM) on all channels
KBI
— 7-pin keyboard interrupt module
Up to 38 general-purpose input/output (I/O)
pins
Software selectable pullups on ports when
used as inputs
Software selectable slew rate control on ports
when used as outputs
Software selectable drive strength on ports
when used as outputs
Master reset pin and power-on reset (POR)
Internal pullup on RESET, IRQ, and BKGD/MS
pins to reduce customer system cost
48-pin quad flat no-lead package (QFN)
44-pin low-profile quad flat package (LQFP)
42-pin shrink dual-in-line package (SDIP)
32-pin low-profile quad flat package (LQFP)
