C8051T623
C8051T622/3 and C8051T326/7
Full Speed USB EPROM MCU Family
USB Function Controller
- USB specification 2.0 compliant
- Full speed (12 Mbps) or low speed (1.5 Mbps) oper-
ation
- 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 plat-
form; Complete development kit available
- On-chip debug circuitry facilitates full speed, non-
intrusive in-system debug
- Provides breakpoints, single stepping,
inspect/modify memory and registers
High-Speed 8051 µC Core
- Pipelined instruction architecture; executes 70% of
instructions in 1 or 2 system clocks
- Up to 48 MIPS throughput with 48 MHz clock
- Expanded interrupt handler
Memory
- 1280 Bytes internal data RAM (256 + 1024)
- 16/8 kB byte-programmable EPROM code memory
- EPROM can be programmed from firmware running
on the device
Digital Peripherals
- Up to 16 Port I/O with high sink current capability
- Hardware enhanced SPI™, SMBus™, and two
enhanced UART serial ports
- Four general purpose 16-bit counter/timers
- 16-Bit programmable counter array (PCA) with three
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
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
Supply Voltage 1.8 to 5.25 V
- On-chip LDO for internal core supply
- Built-in supply voltage monitor
Package Options:
- 4 x 4 mm QFN24
- 5 x 5 mm QFN28
Temperature Range: –40 to +85 °C
