C8051F311-GMR

C8051F311-GMR is a highly integrated mixed-signal 8bit microcontroller (MCU) featuring a powerful 8051 core with 25MHz performance. The MCU offers 16KB flash, 1.25KB RAM along with additional communication interfaces and 4 x 16bit timers in a 5x5 mm, QFN28 package. On-chip analogue features include a 10-bit, 17-channel, 200Ksps ADC and 2 comparators. With on-chip Power-On Reset, VDD monitor, watchdog timer, and a ±2 internal oscillator, this MCU is a truly stand-alone system-on-chip solution, making it ideal for applications such as battery chargers, electronic toys and games, motor control, and optical communications.

• VREF from external pin or VDD, built-in temperature sensor, external conversion start input
• Programmable hysteresis and response time, configurable as interrupt or reset source (Comparator0)
• On-chip debug circuitry facilitates full speed, non-intrusive in-system debug (no emulator required)
• Supply voltage range from 2.7 to 3.6V, typical operating current is 5mA at 25MHz
• Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
• Hardware enhanced UART, SMBus™, and SPI™ serial ports
• Can switch between clock sources on-the-fly; useful in power saving modes
• External oscillator: Crystal, RC, C, or clock (1 or 2 pin modes)
• Temperature rating range from -40 to +85°C
