General Description
• One 16-bit, 6-channel timer interface module (TIM2) with selectable input capture, output compare,
and pulse-width modulation (PWM) capability on each channel
• 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 crystal
• 24-channel, 10-bit successive approximation analog-to-digital converter (ADC)
• 8-bit keyboard wakeup port with software selectable rising or falling edge detect, as well as high or
low level detection
• Up to 53 general-purpose input/output (I/O) pins, including:
– 40 shared-function I/O pins, depending on package choice
– Up to 13 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.
• Internal pullups on IRQ and RST to reduce customer system cost
• High current 10-mA sink/source capability on all port pins
• Higher current 20-mA sink/source capability on PTC0–PTC4 and PTF0–PTF3
• User selectable clockout feature with divide by 1, 2, and 4 of the bus frequency or the crystal
frequency
• User selection of having the oscillator enabled or disabled during stop mode
• BREAK module (BRK) to allow single breakpoint setting during in-circuit debugging
• Available packages:
– 32-pin low-profile quad flat pack (LQFP)
– 48-pin low-profile quad flat pack (LQFP)
– 64-pin quad flat pack (QFP)
• Specific features in 32-pin LQFP are:
– Port A is only 4 bits: PTA0–PTA3; shared with ADC and KBI modules
– Port B is only 6 bits: PTB0–PTB5; shared with ADC module
– Port C is only 2 bits: PTC0–PTC1; shared with MSCAN08 module
– Port D is only 7 bits: PTD0–PTD6; shared with SPI, TIM1 and TIM2 modules
– Port E is only 2 bits: PTE0–PTE1; shared with ESCI module
• Specific features in 48-pin LQFP are:
– Port A is 8 bits: PTA0–PTA7; shared with ADC and KBI modules
– Port B is 8 bits: PTB0–PTB7; shared with ADC module
– Port C is only 7 bits: PTC0–PTC6; shared with MSCAN08 module
– Port D is 8 bits: PTD0–PTD7; shared with SPI, TIM1, and TIM2 modules
– Port E is only 6 bits: PTE0–PTE5; shared with ESCI module
• Specific features in 64-pin QFP are:
– Port A is 8 bits: PTA0–PTA7; shared with ADC and KBI modules
– Port B is 8 bits: PTB0–PTB7; shared with ADC module
– Port C is only 7 bits: PTC0–PTC6; shared with MSCAN08 module
– Port D is 8 bits: PTD0–PTD7; shared with SPI, TIM1, andTIM2 modules
– Port E is only 6 bits: PTE0–PTE5; shared with ESCI module
– Port F is 8 bits: PTF0–PTF7; shared with TIM2 module
– Port G is 8 bits; PTG0–PTG7; shared with ADC module
