It integrates UART, I²C, SPI, LIN, RTC, PWM, and on-chip debug for industrial sensor nodes and motor control.
For engineers reviewing the R5F10EGAGNA#20 datasheet, R5F10EGAGNA#20 pinout, R5F10EGAGNA#20 application, or R5F10EGAGNA#20 equivalent, key selection criteria include industrial-grade temperature range (−40°C to +105°C), 48-pin HWQFN package (7 × 7 mm, 0.5 mm pitch), 32 MHz max CPU frequency, and verified support for self-programming and flash shield window functions.
Technical Context
The R5F10EGAGNA#20 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, delivering 41 DMIPS at 32 MHz. Its CPU supports single-cycle 16×16 multiply and MAC operations, 16-bit barrel shift, and 86% of instructions executed in 1–2 clock cycles.
It features dual-clock domains: high-speed on-chip oscillator (32 MHz ±1% over voltage/temperature) and subsystem crystal oscillator (32.768 kHz), enabling precise RTC operation with calendar/alarm and watch correction. Power management includes Stop (0.23 µA), Halt (0.57 µA), and Snooze modes (0.6–0.7 mA).

FAQ
What is the operating temperature range for the R5F10EGAGNA#20?
The R5F10EGAGNA#20 is rated for industrial operation from −40°C to +105°C ambient temperature. This specification is confirmed in the RL78/G1A datasheet (R01DS0151EJ0230 Rev.2.30, Table 1-1 and Section 1.6), and applies specifically to the G-suffix variant such as R5F10EGAGNA#20. The device maintains full functionality-including 32 MHz CPU operation, 12-bit ADC accuracy, and RTC calendar function-across this full range.
Does the R5F10EGAGNA#20 support in-system programming (ISP)?
Yes, the R5F10EGAGNA#20 supports full in-system programming via its on-chip debug interface (TOOL0/P40) and serial wire debug (SWD) protocol. It includes secure boot swap functionality and flash shield window protection, enabling field firmware updates without removing the device from the PCB. These capabilities are documented in Section 1.1 "Features" and Chapter 5 "Flash Memory" of the R01DS0151EJ0230 datasheet.
How many UART interfaces does the R5F10EGAGNA#20 provide?
The R5F10EGAGNA#20 provides three UART interfaces: UART0 (RxD0/TxD0), UART1 (RxD1/TxD1), and UART2 (RxD2/TxD2). UART2 also supports LIN bus physical layer compliance. All three operate at 7-, 8-, or 9-bit data formats and are independently configurable. This is specified in Section 1.1 "Features" and confirmed in the 48-pin HWQFN pin configuration (Page 8) of the R01DS0151EJ0230 datasheet.
What is the purpose of the REGC pin on the R5F10EGAGNA#20?
The REGC pin on the R5F10EGAGNA#20 connects to an external 0.47–1 µF capacitor tied to VSS to stabilize the internal voltage regulator. This is mandatory for reliable operation and explicitly required in the datasheet's pin configuration diagrams (Pages 6–9) and cautions (Page 6, 8, 10). Failure to connect REGC properly results in unstable core voltage and unpredictable reset behavior.
Can the R5F10EGAGNA#20 generate PWM signals directly?
Yes, the R5F10EGAGNA#20 can generate up to six independent PWM outputs using its Timer Array Unit (TAU) with seven timer output channels (TO00–TO07). PWM resolution and frequency are programmable via timer prescalers and compare registers. This capability is confirmed in Section 1.6 "Outline of Functions" (Page 16) and supported by the TAU block diagram (Page 14) in the R01DS0151EJ0230 datasheet.
