Integrated clock recovery; no external oscillator required for full speed or
low speed
Supports six flexible endpoints
256-byte USB buffer memory
Integrated transceiver; no external resistors required
On-Chip Debug
-
C8051F34A can be used as code development platform; Complete
development kit available
On-chip debug circuitry facilitates full speed, nonintrusive in-system
debug
Provides breakpoints, single stepping, inspect/modify memory and registers
-
Digital Peripherals
-
1280 bytes internal data RAM (256 + 1024)
16 kB byte-programmable EPROM code memory
EPROM can be programmed from firmware running on the device
-
-
Supply Voltage: 1.8 to 5.25 V
-
Two internal oscillators:
• 48 MHz: ±0.25% accuracy with clock recovery enabled. 
Supports all USB and UART modes
• 80/40/20/10 kHz low frequency, low power
External oscillator: Crystal, RC, C, or CMOS Clock
Can switch between clock sources on-the-fly; useful in power saving
modes
