Rev. 1.1 6/08 Copyright © 2008 by Silicon Laboratories C8051F34x
Analog Peripherals
- 10-Bit ADC ('F340/1/2/3/4/5/6/7 only)
• Up to 200 ksps
• Built-in analog multiplexer with single-ended and
differential mode
• VREF from external pin, internal reference, or V
DD
• Built-in temperature sensor
• External conversion start input option
- Two comparators
- Internal voltage reference ('F340/1/2/3/4/5/6/7 only)
- Brown-out detector and POR Circuitry
USB Function Controller
- USB specification 2.0 compliant
- Full speed (12 Mbps) or low speed (1.5 Mbps) operation
- Integrated clock recovery; no external crystal required for
full speed or low speed
- Supports eight flexible endpoints
- 1 kB USB buffer memory
- Integrated transceiver; no external resistors required
On-Chip Debug
- On-chip debug circuitry facilitates full speed, non-intru-
sive 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
Voltage Supply Input: 2.7 to 5.25 V
- Voltages from 3.6 to 5.25 V supported using On-Chip
Voltage Regulator
HIgh Speed 8051 µC Core
- Pipelined instruction architecture; executes 70% of
Instructions in 1 or 2
system clocks
- 48 MIPS and 25 MIPS versions available.
- Expanded interrupt handler
Memory
- 4352 or 2304 Bytes RAM
- 64 or 32 kB Flash; In-system programmable in 512-byte
sectors
Digital Peripherals
- 40/25 Port I/O; All 5 V tolerant with high sink current
- Hardware enhanced SPI™, SMBus™, and one or two
enhanced UART serial ports
- Four general purpose 16-bit counter/timers
- 16-bit programmable counter array (PCA) with five cap-
ture/compare modules
- External Memory Interface (EMIF)
Clock Sources
- Internal Oscillator: ±0.25% accuracy with clock recovery
enabled. Supports all USB and UART modes
- External Oscillator: Crystal, RC, C, or clock (1 or 2 Pin
modes)
- Low Frequency (80 kHz) Internal Oscillator
- Can switch between clock sources on-the-fly
Packages
- 48-pin TQFP (C8051F340/1/4/5/8)
