See all from this product rangeProduct Overview
The C8051F921-GM is an ultra-low power 8-bit Microcontroller 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 32kB flash, 4.25kB RAM and a 10-bit 15-channel 300ksps ADC. The C8051F921-GM operates down to 0.9V and up to 3.6V, enabling single- cell battery operation as well as dramatically increasing the battery life for dual-cell applications. With an integrated dc-dc converter and low energy modes to reduce the active and sleep currents. With on-chip power-on reset, VDD monitor, watchdog timer and clock oscillator, the device is truly stand-alone system-on-a-chip solutions. The flash memory can be reprogrammed even in-circuit, providing non-volatile data storage and also allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals and may individually shut down any or all peripherals for power savings.

- Up to 25MIPS throughput with 25MHz clock
- Expanded interrupt handler
- Two comparators
- 6-bit Programmable current reference
- On-chip Debug circuitry facilitates full-speed, nonintrusive in-system debug
- Provides breakpoints, single stepping
- Inspect/Modify memory and registers
- Hardware SMBus™ (I²C™ Compatible), 2 x SPI™ and UART serial ports available concurrently
- Four general purpose 16-bit counter/timers
- Programmable 16-bit counter/timer array with six capture/compare modules and watchdog timer
- Hardware SmaRTClock operates down to 0.9V and requires less than 0.5µA supply current
- Internal oscillators - 24.5MHz, 2% accuracy supports UART operation
- External oscillator - Crystal, RC, C or CMOS clock
- SmaRTClock oscillator - 32kHz crystal or internal self-oscillate mode
- Can switch between clock sources on-the-fly - useful in implementing various power saving modes
