C8051F336/7/8/9
Rev. 1.0 9/08 Copyright © 2008 by Silicon Laboratories C8051F336/7/8/9
Analog Peripherals
-
10-Bit ADC (‘F336/8 only)
• Up to 200 ksps
• Up to 20 external single-ended or differential inputs
• VREF from on-chip VREF, external pin or V
DD
• Internal or external start of conversion source
• Built-in temperature sensor
- 10-Bit Current Output DAC (‘F336/8 only)
- Comparator
• Programmable hysteresis and response time
• Configurable as interrupt or reset source
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
-
Built-in voltage supply monitor
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
Temperature Range: –40 to +85 °C
Memory
-
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™ (I
2
C compati-
ble), 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
20 or 24-Pin QFN (4 x 4 mm)
