17 1. System Overview C8051F70x/71x devices are fully integrated, system-on-a-chip, capacitive sensing mixed-signal MCUs. Highlighted 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 25 MIPS) In-system, full-speed, non-intrusive debug interface (on-chip) Capacitive Sense interface with 38 input channels 10-bit 500 ksps single-ended ADC with 16 external channels and integrated temperature sensor Precision calibrated 24.5 MHz internal oscillator 16 kb of on-chip Flash memory 512 bytes of on-chip RAM SMBus/I 2 C, Enhanced UART, and Enhanced SPI serial interfaces implemented in hardware Four general-purpose 16-bit timers Programmable Counter/Timer Array (PCA) with three capture/compare modules On-chip internal voltage reference On-chip Watchdog timer On-chip Power-On Reset and Supply Monitor On-chip Voltage Comparator 54 general purpose I/O With on-chip power-on reset, V DD monitor, watchdog timer, and clock oscillator, the C8051F70x/71x devices are truly stand-alone, system-on-a-chip solutions. The Flash memory can be reprogrammed even in-circuit, providing 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 C8051F70x/71x 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, and 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 V operation over the industrial temperature range ( 45 to +85 C). An 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 2 V above the V DD supply, with the exception of P0.3. See Table 2.1 for ordering information. Block diagrams of the devices in the C8051F70x/71x family are shown in Figure 1.1. Rev
