Full Speed USB EEPROM MCU Family
USB Function Controller
High-Speed 8051 µC Core
-
-
-
USB specification 2.0 compliant
-
Pipelined instruction architecture; executes 70% of instructions in 1 or 2
system clocks
Up to 48 MIPS throughput with 48 MHz clock
Full speed (12 Mbps) or low speed (1.5 Mbps) operation
-
-
Integrated clock recovery; no external oscillator required for full speed or
low speed
Supports six flexible endpoints
Expanded interrupt handler
-
-
-
Digital Peripherals
-
-
256-byte USB buffer memory
Up to 16 port I/O with high sink current capability
Integrated transceiver; no external resistors required
Hardware enhanced SPI™, SMBus™, and two enhanced UART serial
ports
Four general purpose 16-bit counter/timers
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 regis-
ters
16-bit programmable counter array (PCA) with five capture/compare
modules and enhanced PWM functionality
Clock Sources
-
Two internal oscillators:
•
48 MHz: ±0.25% accuracy with clock recovery enabled.
Supports all USB and UART modes
Memory
-
-
-
1280 bytes internal data RAM (256 + 1024)
•
80/40/20/10 kHz low frequency, low power
16 kB byte-programmable EPROM code memory
-
-
External oscillator: Crystal, RC, C, or CMOS Clock
EPROM can be programmed from firmware running on the device
Can switch between clock sources on-the-fly; useful in power saving
modes
