• Low-power design; fully static with stop and wait modes
• Standard low-power modes of operation:
– Wait mode
– Stop mode
• Master reset pin and power-on reset (POR)
• 20 Kbytes of on-chip FLASH memory with in-circuit programming
capabilities of FLASH program memory
• 512 bytes of on-chip random-access memory (RAM)
• Serial peripheral interface module (SPI)
• Serial communications interface module (SCI)
• Two 16-bit, 2-channel timer interface modules (TIM1 and TIM2)
with selectable input capture, output compare, and PWM
capability on each channel
• 8-channel, 8-bit successive approximation analog-to-digital
converter (ADC)
• BREAK module (BRK) to allow single breakpoint setting during
in-circuit debugging
• Internal pullups on IRQ and RST to reduce customer system cost
• Clock generator module with on-chip 32-kHz crystal compatible
PLL (phase-lock loop)
• Up to 33 general-purpose input/output (I/O) pins, including:
– 26 shared-function I/O pins
– Five or seven dedicated I/O pins, depending on package
choice
• Selectable pullups on inputs only on ports A, C, and D. Selection
is on an individual port bit basis. During output mode, pullups are
disengaged.
• High current 10-mA sink/10-mA source capability on all port pins
• Higher current 15-mA sink/source capability on PTC0–PTC4
• Timebase module with clock prescaler circuitry for eight user
selectable periodic real-time interrupts with optional active clock
source during stop mode for periodic wakeup from stop using an
external 32-kHz crystal
