C8051F981-C-GM is an ultra-low power microcontroller (MCU) that has been designed from the ground up to be highly power-effective. The MCU features a powerful 8051 core with 25MHz performance along with 8KB flash, 0.5KB RAM and a - ADC in a 3x3 mm, QFN20 package. With very low active and sleep currents and fast wake-up times, this is ideal for applications such as water/gas meters, sensor interfaces, alarm systems portable healthcare products and other low-power applications.
- Built-in LDO regulator allows a high analogue supply voltage and low digital core voltage
- 2 built-in supply monitors (brownout detector) for sleep mode and active modes
- Data-dependent windowed interrupt generator, built-in temperature sensor
- Supports buttons, slider, wheel, capacitive proximity sensing, fast 40µs per channel conversion time
- Programmable hysteresis and response time, configurable as wake-up or reset source comparator
- Up to ±500µA, can be used as a bias or for generating a custom reference voltage
- Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
- Hardware SMBus�/I2C�, SPI�, and UART serial ports available concurrently
- On-chip debug circuitry facilitates full-speed, nonintrusive in-system debug (no emulator required)
- Temperature rating range from -40 to +85°C
