C8051F330-GMR 25MHz 8-Bit 8051 Microcontroller MCU with 8KB Flash and QFN-20 Package for Embedded Control

C8051F330-GMR Microcontroller MCU 25MHz 8-Bit 8051 Microcontroller IC QFN-20 Mixed-Signal ISP Flash MCU

The C8051F330 is an 8-bit, 8051-compatible mixed-signal microcontroller (MCU) housed in a compact 20-pin QFN package. It integrates 8 kB of Flash memory, a 10-bit ADC, a comparator, an internal oscillator, and a variety of serial interfaces, making it well suited for compact, low-pin-count embedded applications that require analog acquisition and control.

• Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
• Up to 25 MIPS throughput with a 25 MHz clock
• Expanded interrupt handler

• 768 bytes internal data RAM (256 + 512)
• 8 kB ('F330/1), 4 kB ('F332/3), or 2 kB ('F334/5) Flash; in-system programmable in 512-byte sectors — 512 bytes are reserved in the 8 kB devices

• 17 Port I/O; all 5 V tolerant with high sink current
• Hardware-enhanced UART, SMBus™, and enhanced SPI™ serial ports
• Four general-purpose 16-bit counter/timers
• 16-bit programmable counter array (PCA) with three capture/compare modules
• Real-time clock mode using PCA or timer and external clock source

• Two internal oscillators:
  • 24.5 MHz with ±2% accuracy, supporting crystal-less UART operation
  • 80/40/20/10 kHz low-frequency, low-power
• External oscillator: crystal, RC, C, or clock (1- or 2-pin modes)
• Can switch between clock sources on the fly; useful in power-saving modes

• 10-bit ADC ('F330/2/4 only)
  • Up to 200 ksps
  • Up to 16 external single-ended or differential inputs
