Silicon Laboratories C8051F330D User Manual
C8051F330D
25 MIPS, 8 kB Flash, 10-Bit ADC, 20-Pin Mixed-Signal MCU
Analog Peripherals
10-Bit ADC
- Programmable throughput up to 200 ksps
- Up to 16 external inputs; programmable as single-ended or differential
- Reference from internal V
, VDD, or external pin
REF
- Internal or external start of conversion sources
- Built-in temperature sensor (±3 °C)
10-bit DAC (Current Mode)
Comparator
- Programmable hysteresis and response time
- Configurable to generate interrupts or reset
- Low current (0.4 µA)
On-Chip Debug
- On-chip debug circuitry facilitates full speed, non-intrusive in-system
debug (no emulator required)
- Provides breakpoints, single stepping, watchpoints
- Inspect/modify memory, registers, and stack
- Superior performance to emulation systems using ICE-chips, target
pods, and sockets
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 data RAM
- 8 kB Flash; in-system programmable in 512 byte sectors (512 bytes are
reserved)
Digital Peripherals
- 17 port I/O; all are 5 V tolerant
- Hardware SMBus™ (I2C™ compatible), SPI™, and UART serial ports
available concurrently
- Programmable 16-bit counter/timer array with three capture/compare
modules, WDT
- 4 general-purpose 16-bit counter/timers
- Real-time clock mode using PCA or timer and external clock source
Clock Sources
- Two internal oscillators:
-24.5 MHz, 2% accuracy supports UART operation
-80 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
Package
- 20-pin DIP (lead-free package)
