Overview
R5F21336CNFP#10 from Renesas Electronics is a 16-bit R8C/27 Group single-chip microcontroller with 32 KB flash program memory, 1.5 KB RAM, and dual 1 KB data flash blocks. It features an 89-instruction R8C CPU core, 12-channel 10-bit A/D converter, hardware LIN module (using Timer RA and UART0), and operates from 2.2 V to 5.5 V across −40°C to +85°C ambient temperature. It targets embedded control in automotive body electronics and industrial sensor nodes.
For engineers reviewing the R5F21336CNFP#10 datasheet, R5F21336CNFP#10 pinout, R5F21336CNFP#10 application, or R5F21336CNFP#10 equivalent, this page delivers verified technical context, validated pin functions, confirmed operating parameters, and real-world use cases aligned to the R8C/27 Group specification dated Sep 26, 2008 (Rev.2.10).
Technical Context
The R5F21336CNFP#10 implements the R8C CPU core with two register banks, 20-bit program counter, and 11-bit flag register supporting carry, zero, sign, overflow, and interrupt priority level (IPL) flags. It integrates three independent clock generation circuits: XIN-based crystal/resonator oscillator, high-speed on-chip oscillator with frequency adjustment, and XCIN/XCOUT 32 kHz RTC oscillator (D version).
Peripheral integration includes Timer RA (8-bit, LIN-capable), Timer RB (8-bit), Timer RC (16-bit with input capture/output compare), Timer RE (real-time clock + compare match), two UART channels, one I²C bus interface, one clock-synchronous serial I/O with chip select, and 25 configurable CMOS I/O pins plus 3 dedicated input-only pins - all mapped to a 32-pin LQFP package (PLQP0032GB-A).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21276SDFP | Same R8C/27 Group, identical 32 KB flash + 2×1 KB data flash, but D version (−40°C to +85°C) without N suffix; PLQP0032GB-A package | No factory-programmed user ROM; requires full firmware load post-manufacture | Select when full control over initial firmware image is required and extended temperature range is mandatory. |
| R5F21336CNFP#30 | Identical electrical and functional spec; #30 denotes tape-and-reel packaging vs. #10 tube packaging - same die, same timing, same pinout | No functional difference; only logistics-level distinction in delivery format | Select #30 for automated SMT assembly; #10 remains optimal for prototyping and low-volume hand-soldering. |
Compared with R5F21336CNFP#10, R5F21276SDFP offers identical peripheral set and memory but lacks pre-programmed ROM, while R5F21336CNFP#30 differs solely in packaging - both require no PCB or firmware changes for drop-in substitution in compatible logistics contexts.

FAQ
What is the maximum operating frequency and corresponding supply voltage for R5F21336CNFP#10?
The R5F21336CNFP#10 achieves a minimum instruction execution time of 50 ns at 20 MHz, requiring VCC = 3.0 V to 5.5 V. At lower frequencies (e.g., 10 MHz), it supports down to 2.7 V, and at 5 MHz, it operates from 2.2 V - making R5F21336CNFP#10 suitable for wide-input-voltage battery systems.
Does R5F21336CNFP#10 include factory-programmed firmware?
Yes, R5F21336CNFP#10 includes user ROM programmed before shipment, as confirmed in Table 1.4 of the R8C/27 Group documentation. This pre-loaded firmware distinguishes it from variants like R5F21276SDFP, which require full external programming.
How many A/D input channels does R5F21336CNFP#10 support, and what is their resolution?
R5F21336CNFP#10 integrates a single 10-bit A/D converter with 12 analog input channels (AN0 through AN11), accessible via dedicated pins across Ports P0, P1, and P3 - enabling simultaneous monitoring of multiple sensors without external multiplexing.
Is R5F21336CNFP#10 pin-compatible with other R8C/27 Group MCUs in the same package?
Yes, all R8C/27 Group devices in the PLQP0032GB-A (32-pin LQFP) package - including R5F21272SNFP, R5F21276SDFP, and R5F21336CNFP#10 - share identical pin assignments and electrical characteristics, allowing direct substitution where memory and temperature grade requirements align.
What clock sources are available for the real-time clock (RTC) function in R5F21336CNFP#10?
R5F21336CNFP#10 supports RTC operation using the dedicated 32 kHz XCIN/XCOUT crystal oscillator circuit, available only in N and D versions. The RTC is implemented within Timer RE, providing autonomous timekeeping independent of the main CPU clock domain.
