C8051F99x-C8051F98x Ultra Low Power, 8-2 kB Flash, Capacitive Sensing MCU
▲C8051F99x-C8051F98x devices are fully integrated mixed-signal system-on-a-chip MCUs. Highlighted features are listed below. Refer to Table 2.1 for specific product feature selection and part ordering numbers.
●Ultra low power consumption in active and sleep modes.
●High-speed pipelined 8051-compatible microcontroller core (up to 25 MIPS)
●In-system, full-speed, non-intrusive debug interface (on-chip)
●10-bit 300 ksps or 12-bit 75 ksps single-ended ADC with analog multiplexer
●6-bit programmable current reference (resolution can be increased with PWM)
●Precision programmable 24.5 MHz internal oscillator with spread spectrum technology.
●8 kB, 4 kB, or 2 kB of on-chip Flash memory
●512 bytes of on-chip RAM
●SMBus/I2C, 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 and watchdog timer function
●On-chip power-on reset, VDD monitor, and temperature sensor
●One on-chip voltage comparator
●Up to 14 Capacitive Touch Inputs
●Up to 17 Port I/O
▲ With on-chip power-on reset, VDD monitor, watchdog timer, and clock oscillator, the C8051F99x- C8051F98x 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 on-chip Silicon Labs 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 without occupying package pins.
▲Each device is specified for 1.8 to 3.6 V operation over the industrial temperature range (–40 to +85 °C). The Port I/O and RST pins are powered from the supply voltage. The C8051F99x-C8051F98x devices are available in 20-pin or 24-pin QFN or 24-pin QSOP packages. All package options are lead-free and RoHS compliant. See Table 2.1 for ordering information. Block diagrams are included in Figure 1.1 through Figure 1.9.
