C8051T622/3 and C8051T326/7 Full Speed USB EPROM MCU Family
■System Overview
▲C8051T622/3 and C8051T326/7 devices are fully integrated mixed-signal System-on-a-Chip MCUs. High-lighted features are listed below. Refer to Table 2.1 for specific product feature selection and part ordering numbers.
◆High-speed pipelined 8051-compatible microcontroller core (up to 48 MIPS)
◆In-system, full-speed, non-intrusive debug interface (on-chip)
◆C8051F34A ISP flash device is available for quick in-system code development
◆Universal Serial Bus (USB) Function Controller with six flexible endpoint pipes, integrated transceiver, and 256-Byte FIFO RAM
◆Supply Voltage Regulator
◆Precision calibrated 48 MHz internal oscillator
◆Internal low-frequency oscillator for additional power savings
◆16 kB or 8 kB of on-chip byte-programmable EPROM—(512 bytes are reserved)
◆1280 bytes of on-chip RAM (256 + 1 kB)
◆SMBus/I2C, 2 UARTs, and Enhanced SPI serial interfaces implemented in hardware
◆Four general-purpose 16-bit timers
◆Programmable Counter/Timer Array (PCA) with three capture/compare modules and Watchdog Timer function
◆On-chip Power-On Reset and V-DD Monitor
◆Up to 16 Port I/O
▲With on-chip Power-On Reset, V-DD monitor, Watchdog Timer, and clock oscillator, the C8051T622/3 and C8051T326/7 devices are truly stand-alone System-on-a-Chip solutions. User software has complete control of all peripherals, and may individually shut down any or all peripherals for power savings.
▲Code written for the C8051T622/3 and C8051T326/7 family of processors will run on the C8051F34A Mixed-signal ISP Flash microcontroller, providing a quick, cost-effective way to develop code without requiring special emulator circuitry. The C8051T622/3 and C8051T326/7 processors include Silicon Laboratories’ 2-Wire C2 Debug and Programming interface, which 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 of memory, viewing and modification of special function 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 without occupying package pins.
▲Each device is specified for 1.8-to-5.25 V operation over the industrial temperature range (–40 to +85 °C). For voltages above 3.6 V, the on-chip Voltage Regulator must be used. A minimum of 3.0 V is required for USB communication. An additional internal LDO is used to supply the processor core voltage at 1.8 V. The Port I/O and RST pins are tolerant of input signals up to 5 V. The C8051T622/3 are available in 24-pin QFN packaging and the C8051T326/7 are available in 28-pin QFN packaging. See Table 2.1 for ordering information. A block diagram is shown in Figure 1.1.
