Single/Dual Battery, 0.9-3.6 V, 32 kB, smaRTClock, 10-Bit ADC MCU

Supply Voltage: 0.9 to 3.6 V

- One-cell mode supports 0.9–1.8 V operation

- Two-cell mode supports 1.8–3.6 V operation

- Built-in dc-dc converter with 1.8 –3.3 V output (65 mW max) for use in one-cell mode; can supply external devices

- Typical sleep mode current < 0.1 μA; retains state and RAMcontents over full supply range; fast wakeup

- 2 built-in brown-out detectors cover sleep and active modes

10-Bit Analog to Digital Converter

- Up to 300 ksps

- Up to 23 external inputs

- External pin or internal VREF (no external capacitor required)

- Built-in temperature sensor

- External conversion start input option

- Autonomous Burst Mode with 16-bit automatic averaging accumulator

Two Comparators

- Programmable hysteresis and response time

- Configurable as interrupt or reset source

- Low current (< 0.5 μA)

- Up to 23 Capacitive Touch Sense inputs

Memory

- 4352 bytes internal data RAM (256 + 4K)

- 32 kB bytes Flash; In-system programmable in 1024-byte sectors; Full read/write/erase functionality over the entire supply range

- External memory interface (multiplexed address/data)

On-Chip Debug

- On-chip debug circuitry facilitates full speed, non-intrusive insystem debug (no emulator required)
