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

High-Speed 8051 µC Core

Pipelined instruction architecture; executes 70% of

Memory

1536 bytes internal RAM

instructions in 1 or 2 system clocks

Up to 25 MIPS throughput with 25 MHz clock

Expanded interrupt handler

(1 k + 256 + 256 USB FIFO)

16k bytes Flash; In-system programmable in

512-byte sectors

On-Chip Debug

On-chip debug circuitry facilitates full speed,

non-intrusive in-system debug (no emulator

required)
