C8051F330-GMR Full Speed USB Flash MCU Famil
Analog Peripherals
- 10-Bit ADC (‘F330/2/4 only)
• Up to 200 ksps
• Up to 16 external single-ended or differential inputs
• VREF from internal VREF, external pin or VDD
• Internal or external start of conversion source
• Built-in temperature sensor - 10-Bit Current Output DAC (‘F330
only) - Comparator
• Programmable hysteresis and response time
• Configurable as interrupt or reset source
• Low current (0.4 µA) On-Chip Debug
- On-chip debug circuitry facilitates full speed, nonintrusive
in-system debug (no emulator required)
- Provides breakpoints, single stepping, inspect/modify memory and
registers
- Superior performance to emulation systems using ICE-chips, target
pods, and sockets
- Low cost, complete development kit Supply Voltage 2.7 to 3.6 V
- Typical operating current: 6.4 mA at 25 MHz; 9 µA at 32 kHz
- Typical stop mode current: 0.1 µA
Temperature Range: –40 to +85 °C
High Speed 8051 µC Core
- Pipelined instruction architecture; executes 70% of instructions
in 1 or 2 system clocks
- Up to 25 MIPS throughput with 25 MHz clock
- Expanded interrupt handler Memory
- 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 Digital Peripherals
- 17 Port I/O; All 5 V tolerant with high sink curren
t - 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
Clock Sources
- Two internal oscillators:
• 24.5 MHz with ±2% accuracy supports 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
