Product details
Overview
R4F20323RNFE#V0 from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/Tiny series, designed for embedded control in resource-constrained industrial and consumer systems. It integrates 128 KB flash memory, 8 KB RAM, a 32 MHz max CPU clock, 16-channel 10-bit ADC, and supports CAN 2.0B interface via integrated CAN controller. It operates across −40°C to +85°C and targets motor control and sensor interface applications.
For engineers reviewing the R4F20323RNFE#V0 datasheet, R4F20323RNFE#V0 pinout, R4F20323RNFE#V0 application, or R4F20323RNFE#V0 equivalent, key selection criteria include its H8S/20323R core architecture, 100-pin LQFP package with dedicated CAN_TX/CAN_RX pins, flash endurance (10,000 write/erase cycles), and support for on-chip debugging via JTAG interface.
Technical Context
The R4F20323RNFE#V0 implements the H8S/2000 CPU core with 16-bit data bus and 24-bit address space, enabling up to 16 MB linear addressing. It includes an on-chip clock pulse generator (CPG) supporting crystal, ceramic resonator, or external clock inputs, and features a programmable watchdog timer (WDT) with independent reset and interrupt modes.
Peripheral integration includes three 16-bit timer units (each with compare match and input capture), two serial communication interfaces (SCI) with UART/lin functionality, and a 16-channel analog-to-digital converter with sample-and-hold and scan mode. The device uses a unified memory map with separate I/O register space and supports vectored interrupt handling with 128 priority levels.

FAQ
What is the maximum operating frequency of the R4F20323RNFE#V0?
The R4F20323RNFE#V0 supports a maximum CPU clock frequency of 32 MHz when using the on-chip high-speed oscillator or an external crystal source. This frequency is maintained across the full industrial temperature range (−40°C to +85°C) and supply voltage range (2.7 V to 5.5 V), with timing parameters fully characterized in the hardware user's manual Rev.3.00.
Does the R4F20323RNFE#V0 include an integrated CAN transceiver?
No, the R4F20323RNFE#V0 includes only a CAN 2.0B protocol controller-not a physical layer transceiver. External CAN transceivers (e.g., TJA1042, SN65HVD230) must be used to drive the differential CAN_H/CAN_L bus. The MCU provides dedicated CAN_TX and CAN_RX pins (P130/P131) compatible with standard ISO 11898-2 signaling levels.
What debug interface does the R4F20323RNFE#V0 support?
The R4F20323RNFE#V0 supports IEEE 1149.1-compliant JTAG interface for on-chip debugging, flash programming, and boundary-scan testing. It requires a Renesas E1 or E20 emulator for full debug capability, and supports real-time trace, hardware breakpoints, and memory inspection without halting peripheral operation.
Is the R4F20323RNFE#V0 RoHS compliant and lead-free?
Yes, the R4F20323RNFE#V0 is RoHS compliant and lead-free per EU Directive 2011/65/EU. The "#V0" suffix denotes lead-free, halogen-free packaging with matte tin plating on the 100-pin LQFP terminals. Full compliance documentation-including substance declarations and test reports-is available through Renesas' environmental portal.
What is the flash endurance specification for the R4F20323RNFE#V0?
The R4F20323RNFE#V0 specifies 10,000 write/erase cycles for its 128 KB on-chip flash memory under standard operating conditions (25°C, VCC = 3.3 V). Endurance is verified per JEDEC JESD22-A117 and includes margin for operation across the full industrial temperature range, with wear leveling left to application firmware implementation.
