R5F100JGAFA#V0 - 32MHz RL78/G13 128KB Flash MCU | Renesas
MPN: R5F100JGAFA#V0 ✓ Hoạt độngR5F100JGAFA#V0 Tóm tắt
A microcontroller (MCU) is a single-chip computer that combines a CPU, memory (Flash/SRAM), and programmable peripherals on one die. Low-power 16-bit MCUs like the RL78 family sit in the hierarchy: MCU -> embedded controller -> microprocessor family -> semiconductor. The RL78 architecture pairs a CISC-style 16-bit CPU with 78K core heritage, achieving 43.2 DMIPS at 32 MHz while consuming only 66 uA/MHz, making it ideal for battery-powered appliances and IoT endpoints.
Key features of the R5F100JGAFA#V0 include 230 nA STOP-mode current with RAM retention (310 nA with LVD enabled), integrated safety functions that detect illegal hardware operation, on-chip oscillators, a multi-channel A/D converter, timers, and serial interfaces (UART, I2C, CSI/SPI). It supports IEC/UL 60730 safety standards for household appliances. The 52-LQFP package offers 52 pins with 10x10 mm body suitable for hand-soldering or low-density SMT lines.
Typical applications include white goods (washing machines, microwave ovens, induction cookers), smart-metering and energy harvesting, HVAC control boards, battery-powered sensor nodes, and portable medical monitoring peripherals. Designers benefit from a wide voltage range, flexible clock tree, and IEC/UL 60730-capable safety library support.
When designing, follow the RL78 hardware manual's decoupling guidance and route VDD/AVREF separately with local 0.1 uF + 10 uF bulk capacitors near each pin pair. Use the on-chip debugger (TOOL0) header for in-circuit emulation; this eliminates the need for socketed programming during prototyping.

Ứng dụng tiêu biểu
R5F100JGAFA#V0 phù hợp cho 6 Áp dụngs: White Goods - Washing Machine Controller, Smart Metering & Energy Harvesting, HVAC Thermostat Control, Battery-Powered Sensor Nodes, Induction Cooker & Microwave Oven Control, Portable Medical Monitoring Peripherals.
White Goods - Washing Machine Controller
The R5F100JGAFA#V0's 32 MHz RL78 core and IEC/UL 60730-capable safety library make it well-suited for washing machine motor control boards. The 12 KB SRAM handles motor control state machines while the 128 KB Flash stores user-interface firmware and self-test routines. STOP-mode current of 0.23 uA keeps standby power under 0.5 W for ENERGY STAR compliance; designers add external TRIAC drivers for the wash motor.

Smart Metering & Energy Harvesting
Battery-powered smart meters benefit from the R5F100JGAFA#V0's 66 uA/MHz active current and 230 nA STOP-mode draw, extending coin-cell lifetime beyond 10 years. The 8 KB data Flash emulates EEPROM for tamper logs, while 12-channel 10-bit ADC samples CT/voltage sensors directly. On-chip 16 MHz HSI eliminates external crystal, reducing BOM cost for harvesting designs where every uA counts.
Được đề xuất
HVAC Thermostat Control
The R5F100JGAFA#V0 drives HVAC thermostat boards via its multi-channel ADC for temperature sensing and PWM outputs for triac control of fans and compressors. The 1.6 V to 5.5 V supply range lets the same firmware run on 3.3 V battery backup or 5 V USB-powered units. Hardware CRC and illegal-memory-access detection support IEC 60730 Class B for safety-critical HVAC circuits.
Được đề xuất
Battery-Powered Sensor Nodes
Wireless sensor nodes built on the R5F100JGAFA#V0 leverage 0.23 uA STOP current and fast wake-up (under 5 us) to support duty-cycled LoRa/Zigbee transmissions. The 12 KB SRAM buffers sensor frames while 128 KB Flash stores firmware and over-the-air update images. Integrated CSI/SPI and UART/I2C directly interface to popular sub-GHz radios without external glue logic.
Được đề xuất
Induction Cooker & Microwave Oven Control
The R5F100JGAFA#V0's 43.2 DMIPS performance handles induction cooker coil resonant control loops and microwave magnetron timing in real time. Hardware illegal-operation detection plus the IEC/UL 60730 self-test library provide the diagnostic coverage required by kitchen-appliance safety standards. Multi-channel PWM outputs directly drive IGBT gate drivers for the heating element.
Được đề xuất
Portable Medical Monitoring Peripherals
Portable glucose meters and pulse-oximeter peripherals benefit from the R5F100JGAFA#V0's low active current and wide 1.6 V to 5.5 V supply range, supporting direct Li-ion or 2x AA battery operation. The integrated 10-bit ADC and on-chip reference digitize sensor signals without external components. Hardware AES and CRC accelerate secure data transmission to mobile devices.

Ghi chú thiết kế
Place a 0.1 uF ceramic decoupling capacitor as close as possible to each VDD/VSS pin pair, plus a single 10 uF bulk capacitor within 10 mm of the package. The RL78/G13 datasheet specifies that AVREF and VDD must each have their own local bypass; sharing a single capacitor can inject analog noise into the ADC reference. For STOP-mode designs, ensure no floating analog inputs - tie unused ANI pins to AVSS to prevent parasitic current.
Route the RESET line with a short trace and a 10 kohm pull-up to VDD; add a 0.1 uF capacitor to VSS for noise immunity. The TOOL0 pins (P35/P36) used for on-chip debugging should be routed to a 2x3 or 2x5 header matching the RL78 OCD pinout for in-circuit emulation - this eliminates socketed programming during prototyping.
Do not exceed 5.5 V on any pin; absolute maximum VDD is 6.0 V per the datasheet. When migrating between RL78/G13 variants, verify peripheral mapping - R5F100JGAFA#V0 may have different timer channel counts than the LQFP-64 cousins. Always enable the LVD before STOP mode if you need brown-out recovery on wake.
Thông tin tuân thủ
RoHS and REACH compliant per Renesas product page. IEC/UL 60730 capable for household appliance safety; not AEC-Q100 qualified (use automotive-grade RL78/F1x for that).
