Product details
Overview
R5F21262SYFP#X6 from Renesas Electronics is a 16-bit single-chip microcontroller in the R8C/26 Group, featuring an R8C CPU core, 8 KB flash program memory, 512 bytes RAM, and operating at up to 20 MHz (VCC = 3.0–5.5 V). It integrates a 10-bit 12-channel ADC, dual UARTs, I²C interface, hardware LIN module, four 8-/16-bit timers, and operates across –40°C to +85°C - deployed in industrial control panels and appliance motor management systems.
For engineers reviewing the R5F21262SYFP#X6 datasheet, R5F21262SYFP#X6 pinout, R5F21262SYFP#X6 application, or R5F21262SYFP#X6 equivalent, key selection criteria include its 32-pin LQFP package, absence of on-chip data flash (distinguishing it from R8C/27), support for XCIN/XCOUT real-time clock circuitry (D version), and compatibility with Renesas' standard R8C toolchain and debug interfaces.
Technical Context
The R5F21262SYFP#X6 implements the R8C CPU core with 89 fundamental instructions and executes at minimum 50 ns per instruction (20 MHz XIN, 3.0–5.5 V). Its memory map spans 1 Mbyte, with fixed interrupt vectors at 0FFDCh–0FFFFh and SFRs mapped to 00000h–002FFh.
Peripheral integration includes Timer RE with real-time clock capability (enabled in D version), hardware LIN using Timer RA and UART0, and dual UART channels supporting full-duplex asynchronous communication - all coordinated via seven-level priority interrupt controller with 15 internal, 4 external, and 4 software sources.

FAQ
What is the operating temperature grade of R5F21262SYFP#X6?
R5F21262SYFP#X6 is a D-grade device rated for –40°C to +85°C ambient operation, confirmed by the 'Y' in the part number mapping to Renesas' D-version specification per Table 1.3 and Figure 1.2. This qualifies it for industrial and automotive cabin applications where extended thermal range is mandatory.
Does R5F21262SYFP#X6 include on-chip data flash memory?
No, R5F21262SYFP#X6 belongs to the R8C/26 Group and contains only program flash memory (8 KB). It does not integrate data flash - a feature exclusive to the R8C/27 Group (e.g., R5F21272SDFP). Data storage must be implemented externally or via emulated EEPROM in program flash.
Which clock sources support real-time clock (RTC) functionality in R5F21262SYFP#X6?
R5F21262SYFP#X6 supports RTC operation via Timer RE using the 32 kHz XCIN/XCOUT crystal oscillator circuit - available only in D-version devices like R5F21262SYFP#X6. The XIN/XOUT 20 MHz system clock cannot serve as RTC source; XCIN/XCOUT must be populated for accurate timekeeping.
Can R5F21262SYFP#X6 directly drive LEDs without external components?
Yes, R5F21262SYFP#X6 supports LED drive on P1_0 through P1_7 (8 pins), as specified for D-version devices. These ports provide sufficient sink/source current for standard indicator LEDs, eliminating discrete driver transistors in UI panel designs - verified in Table 1.1 and Figure 1.4 pin assignments.
What debug interface is supported by R5F21262SYFP#X6?
R5F21262SYFP#X6 supports Renesas' standard on-chip debugging interface via the RXD0/TXD0 pins (UART0) and MODE/RESET pins - compatible with E8/E8a debuggers and CS+ IDE. No JTAG or SWD is implemented; debugging relies on Renesas' proprietary serial wire debug protocol over UART.
