Information

C8051F337 devices are fully integrated mixed-signal System-on-a-Chip MCUs. With on-chip Power-On Reset, VDD monitor, Watchdog Timer, and clock oscillator, the C8051F337 devices are 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 ma y individually shut down any or all peripherals for power savings The on-chip Silicon Labs 2-Wire (C2) Development Interface allows non-intrusive (uses no on-chip resources), full speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports inspection and modification of memory and registers, setting breakpoints, single stepping, run and halt commands. All analog and digital peripherals are fully functional while debugging using C2. The two C2 interface pins can be shared with user functions, allowing in-system debugging with-out occupying package pins Each device is specified for 2.7 to 3.6 V operation over the industrial temperature range (–40 to +85°C). The Port I/O and RST pins are tolerant of input signals up to 5 V.

    • 768 bytes internal data RAM (256 + 512)
    • 16 kB Flash; In-system programmable in 512-byte Sectors (512 bytes are reserved) Digital Peripherals
    • 21 or 17 Port I/O; All 5 V tolerant with high sink current
    • Pin-compatible with C8051F330 family of MCUs
    • Hardware enhanced UART, SMBus™ (I2C compatible), and enhanced SPI™ serial ports
    • Four general purpose 16-bit counter/timers
    • 16-Bit programmable counter array (PCA) with three capture/compare modules and enhanced PWM functionality
    • Real time clock mode using timer and crystal Clock Sources
    • 24.5 MHz ±2% Oscillator
  • Supports crystal-less UART operation
  • Low-power suspend mode with fast wake time
    • 80/20/40/10 kHz low-frequency, low-power oscillator
    • 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
