Overview
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.
