C8051F330/1, C8051F330D
8 kB ISP Flash MCU Family
Analog Peripherals
- 10-Bit ADC (‘F330 and ‘F330D 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 and ‘F330D 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, non-
intrusive 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 Flash; In-system programmable in 512-byte
Sectors—512 bytes are reserved
Digital Peripherals
- 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 exter-
nal 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
20-Pin MLP or 20-pin DIP
