imity, and touch screen sensing
- Up to 38 input channels
- Fast 40 µs per channel conversion time
- 12, 13, 14, or 16-bit output
- Auto-scan and wake-on-touch
- Auto-accumulate 4, 8, 16, 32, or 64 samples
10-Bit Analog to Digital Converter
- Up to 500 ksps
- Up to 16 external single-ended inputs
- VREF from on-chip VREF, external pin or VDD
- Internal or external start of conversion source
- Built-in temperature sensor
Analog Comparator
- Programmable hysteresis and response time
- Configurable as interrupt or reset source
On-Chip Debug
- On-chip debug circuitry facilitates full speed, non-
intrusive in-system debug (no emulator required)
- Provides breakpoints, single stepping,
inspect/modify memory and registers
- Superior performance to emulation systems using
ICE-chips, target pods, and sockets
- Low cost, complete development kit
Supply Voltage 1.8 to 3.6 V
- Built-in voltage supply monitor

instructions in 1 or 2 system clocks
- Up to 25 MIPS throughput with 25 MHz clock
- Expanded interrupt handler
Memory
- 512 bytes internal data RAM (256 + 256)
- Up to 16 kB Flash; In-system programmable in 512-
byte Sectors
- Up to 32-byte data EEPROM
Digital Peripherals
- Up to 54 Port I/O with high sink current
- Hardware enhanced UART, SMBus™ (I2C compati-
ble), and enhanced SPI™ serial ports
- Four general purpose 16-bit counter/timers
- 16-Bit programmable counter array (PCA) with 3
capture/compare modules and enhanced PWM
functionality
