Information

C8051F326 devices are fully integrated mixed-signal system-on-a-chip MCUs. High-speed pipelined 8051-compatible microcontroller core (up to 25MIPS), In-system, full-speed, non-intrusive debug interface (on-chip) Universal serial bus (USB) function controller with three fixed-function endpoint pipes, integrated transceiver, and 256B,FIFO RAM, With on-chip power-on reset, VDD monitor, voltage regulator, and clock oscillator, C8051F326 devices are truly stand-alone System-on-a-Chip solutions. The Flash memory can be reprogrammed in-circuit, pro viding non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals, and may individually shut down any or all peripherals for power savings The on-chip Silicon Laboratories 2-Wire (C2) Development Interface allows non-intrusive (uses no on-chip resources), full speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports inspection and modification of memory and registers, setting breakpoints, single stepping, run and halt commands. All analog and digital peripherals are fully functional while debugging using C2. The two C2 interface pins can be shared with user functions, allowing in-system debugging with-out occupying package pins Each device is specified for 2.7–5.25 V operation over the industrial temperature range (–40 to +85°C). For voltages above 3.6V, the on-chip Voltage regulator must be used. A minimum of 3.0 V is required for USB communication. The Port I/O and RST pins are tolerant of input signals up to 5V. C8051F326 are available in two 28-pin QFN packages with different pinouts. The RoHS compliant devices are marked with a -GM suffix in the part number. The port I/O on C8051F326 devices is powered from a separate I/O supply allowing it to interface to low voltage logic
