C8051F327
C8051F326/7
Full Speed USB, 16 kB Flash MCU Family
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 three fixed-function endpoints
- 256 Byte USB buffer memory
- Integrated transceiver; no external resistors
required
On-Chip Debug
- On-chip debug circuitry facilitates full speed,
non-intrusive 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
- Up to 25 MIPS throughput with 25 MHz clock
- Expanded interrupt handler
Memory
- 1536 bytes internal RAM
(1 k + 256 + 256 USB FIFO)
- 16k bytes Flash; In-system programmable in
512-byte sectors
Digital Peripherals
- 15 Port I/O; All 5 V tolerant with high sink current
- Enhanced UART
- Two general purpose 16-bit timers
Clock Sources
- Internal oscillator: 0.25% accuracy with clock
recovery enabled. Supports all USB and UART
modes
- External CMOS clock
- Can switch between clock sources on-the-fly; useful
in power saving strategies
Packages
- 28-pin QFN
- Temperature Range: –40 to +85 °C
