Up to 21 external inputs
VREF from on-chip VREF, external pin, Internal 1.8 V
Regulator or VDD
Internal or external start of conversion source
Built-in temperature sensor
- Comparators
Programmable hysteresis and response time
Configurable as interrupt or reset source
Low current (<0.5 μA)
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 eight flexible endpoints
- 1 kB 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
Supply Voltage 1.8 to 5.25 V
- On-chip LDO for internal core supply
- Built-in supply voltage monitor
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
- Up to 3328 bytes internal data RAM (256 + up to
3072)
- Up to 64 kB byte-programmable EPROM code
memory
- EPROM can be programmed from firmware running
on the device
Digital Peripherals
- 25 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 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
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
Package Options:
- 5 x 5 mm QFN28 or QFN32
- 9 x 9 mm LQFP32
Temperature Range: –40 to +85 °C
