Product details
Overview
R5F101PGAFA#10 from Renesas is a 48-pin LQFP-0.65mm, 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes, integrated RTC, 10-bit ADC (26 channels), and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101PGAFA#10 datasheet, R5F101PGAFA#10 pinout, R5F101PGAFA#10 application, or R5F101PGAFA#10 equivalent, key selection criteria include its 48-pin LQFP package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade (A suffix), and compatibility with Renesas' RL78 toolchain and E2 studio IDE for low-power firmware development.
Technical Context
The R5F101PGAFA#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), 16-bit timer array (12 channels), real-time clock with calendar/alarm, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes UART/LIN (2 channels), I²C/Simplified I²C (up to 10 channels), CSI (2–8 channels), 10-bit ADC with internal 1.45 V reference and temperature sensor, DMA controller (4 channels), and multiplier/divider/MAC unit - all optimized for deterministic real-time control in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PGAFA#10 | Includes 4 KB data flash; otherwise identical pinout, peripherals, and code flash size | Required where EEPROM-like nonvolatile storage for calibration or logging is needed | Select when field data retention across power cycles is mandatory |

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101PGAFA#10?
The R5F101PGAFA#10 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this with a 3-stage pipeline and configurable instruction timing - delivering deterministic real-time response for control loops and communication stacks without requiring external cache or high-speed memory.
Does the R5F101PGAFA#10 include on-chip data flash memory?
No, the R5F101PGAFA#10 does not include on-chip data flash memory. As indicated by the "101" in its part number per Renesas' naming convention, it belongs to the data-flash-free variant of the RL78/G13 family. It retains 64 KB code flash and 4 KB RAM, but nonvolatile data storage requires external EEPROM or FRAM.
What package type and pin count does the R5F101PGAFA#10 use?
The R5F101PGAFA#10 uses a 48-pin LQFP package with 7 mm × 7 mm body size and 0.65 mm lead pitch. The "FA" suffix in the part number explicitly denotes this LQFP-0.65mm variant, distinguishing it from LFQFP (FB), HWQFN (NA), or WFLGA (LA) alternatives in the same family.
What are the supported low-power modes on the R5F101PGAFA#10 and their typical current consumption?
The R5F101PGAFA#10 supports HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. In STOP mode, it maintains RTC timekeeping and voltage monitoring while drawing sub-microamp current - enabling multi-year operation on coin-cell batteries in remote sensing applications.
Can the R5F101PGAFA#10 interface directly with 3.3 V or 1.8 V peripherals?
Yes, the R5F101PGAFA#10 supports different-potential interface operation: its GPIOs can connect directly to 1.8 V, 2.5 V, or 3.0 V logic devices without level shifters. This is enabled by configurable input buffers and N-ch open-drain outputs with VDD-tolerant design, simplifying mixed-voltage system integration.
