Product details
Overview
R5F100PJAFA#10 from Renesas is a 100-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 192 KB flash memory, 8 KB data flash, 16 KB RAM, 52-channel 10-bit ADC, and real-time clock with calendar function. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (0.57 μA in RTC+LVD mode), targeting battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F100PJAFA#10 datasheet, R5F100PJAFA#10 pinout, R5F100PJAFA#10 application, or R5F100PJAFA#10 equivalent, key selection criteria include its 100-pin LQFP package, integrated data flash with 1M rewrite cycles, dual SPI/I²C/UART interfaces, hardware multiplier/divider, and support for -40°C to +85°C industrial ambient operation.
Technical Context
The R5F100PJAFA#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates a 12-bit interval timer, watchdog timer with dedicated low-speed oscillator, background operation for data flash rewriting, and on-chip voltage detector with 14 selectable LVD levels - all coordinated via a centralized power management unit enabling HALT, STOP, and SNOOZE low-power states.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PJAFB#V0 | Same core, memory, and peripherals but in 100-pin LFQFP (0.5-mm pitch); different thermal and mechanical footprint | Preferred where board space constraints favor smaller pitch or higher thermal dissipation is required | Select when PCB layout uses 0.5-mm pitch land pattern and requires improved thermal resistance over LQFP |
| R5F101PJAFA#10 | Omits 8 KB data flash; retains same code flash, RAM, peripherals, and package | Suitable for cost-sensitive designs where non-volatile parameter storage is handled externally or not required | Choose when data logging or field firmware updates are unnecessary - reduces BOM cost by eliminating embedded data flash |
Compared with R5F100PJAFA#10, R5F100PJAFB#V0 offers identical functionality in a denser package requiring tighter layout tolerances, while R5F101PJAFA#10 removes data flash to lower unit cost - making it viable only when external NV memory or simplified firmware update schemes are acceptable.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100PJAFA#10?
The R5F100PJAFA#10 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is measured under standard conditions per Renesas' R01DS0131EJ0380 specification document.
Does the R5F100PJAFA#10 include integrated data flash memory, and what is its endurance specification?
Yes, the R5F100PJAFA#10 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) across the full VDD range of 1.8 V to 5.5 V. This memory supports background operation, allowing program execution from code flash while rewriting data flash - a key feature for robust firmware updates and parameter storage in the R5F100PJAFA#10.
What low-power modes are supported by the R5F100PJAFA#10, and what is the lowest current consumption achievable?
The R5F100PJAFA#10 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active, it consumes just 0.57 μA - verified per the R01DS0131EJ0380 datasheet. This ultra-low quiescent current enables multi-year battery life in always-on sensing applications using the R5F100PJAFA#10.
How many analog input channels does the R5F100PJAFA#10 support, and what ADC resolution is provided?
The R5F100PJAFA#10 integrates a 10-bit successive-approximation ADC with up to 52 configurable analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor - both accessible via dedicated pins - enabling accurate, self-contained environmental monitoring without external components in the R5F100PJAFA#10 design.
Is the R5F100PJAFA#10 pin-compatible with other RL78/G13 variants in the same package, such as R5F100PJAFB#V0?
No, the R5F100PJAFA#10 is not pin-compatible with R5F100PJAFB#V0. Although both are 100-pin devices, R5F100PJAFA#10 uses an LQFP package with 0.65-mm pitch, while R5F100PJAFB#V0 uses LFQFP with 0.5-mm pitch - resulting in incompatible land patterns, solder mask, and mechanical mounting. PCB redesign is required to substitute between these packages of the R5F100PJAFA#10 and R5F100PJAFB#V0.
