Renesas R4F2113NLG#U0

Overview

R4F2113NLG#U0 from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2113 Group, featuring a 27 MHz max CPU clock, 128 KB on-chip flash memory, 8 KB RAM, and integrated peripherals including TPU (16-bit timer pulse unit), SCI (serial communication interface), WDT (watchdog timer), and low-voltage detection circuits. It targets industrial control panels requiring deterministic real-time response, motor drive supervision, and embedded HMI interfaces.

For engineers reviewing the R4F2113NLG#U0 datasheet, R4F2113NLG#U0 pinout, R4F2113NLG#U0 application, or R4F2113NLG#U0 equivalent, key selection criteria include its 100-pin LQFP package, 2.7–5.5 V operating voltage range, -40°C to +85°C industrial temperature grade, and support for both internal and external clock sources with PLL-based frequency multiplication.

Technical Context

The R4F2113NLG#U0 implements the H8S/2000-series CPU core with 32-bit internal data paths and 24-bit addressing, enabling direct access to up to 16 MB of memory space. It integrates a programmable clock pulse generator (CPG) supporting multiple clock sources - main oscillator (1–10 MHz), sub-oscillator (32.768 kHz), and internal RC oscillator - with selectable PLL multiplication ratios (×1 to ×4).

Peripheral subsystems include two independent SCI modules (asynchronous UART mode only), a 16-bit TPU with 8 channels supporting PWM, input capture, and output compare, and dual low-voltage detection circuits (LVD0/LVD1) with independently configurable trip points and interrupt generation. Reset handling includes power-on reset, pin reset, watchdog reset, and two levels of low-voltage detection reset.

FAQ

What is the maximum operating frequency of the R4F2113NLG#U0 and under what conditions?

The R4F2113NLG#U0 achieves a maximum operating frequency of 27 MHz when powered at 4.5–5.5 V with a stable external clock or crystal source. At lower supply voltages (2.7–4.4 V), the maximum frequency is reduced to 20 MHz to maintain timing margin and signal integrity. This specification is verified per the H8S/2113 Group User's Manual Rev.2.00, Section 2.2 and Electrical Characteristics Table 5.1.

Does the R4F2113NLG#U0 support in-system programming of its flash memory?

Yes, the R4F2113NLG#U0 supports in-system programming (ISP) of its 128 KB on-chip flash memory via the on-chip debug interface (OCDS) using standard Renesas E8/E8a emulators or compatible third-party tools. No external programming voltage is required, and the process complies with JEDEC standards for endurance (100,000 cycles) and data retention (20 years at 85°C).

How many serial communication interfaces does the R4F2113NLG#U0 integrate, and what protocols do they support?

The R4F2113NLG#U0 integrates two independent Serial Communication Interfaces (SCI0 and SCI1), each supporting asynchronous UART operation only - no synchronous SPI or I²C modes. Each SCI supports programmable baud rates up to 1 Mbps, 5–9 bit data length, 1–2 stop bits, parity (even/odd/mark/space), and automatic break detection, making them suitable for RS-232 and RS-485 physical layers.

What are the power management modes supported by the R4F2113NLG#U0, and what is the typical current draw in Stop mode?

The R4F2113NLG#U0 supports four power management modes: Normal, Sleep, Stop, and Deep Stop. In Stop mode - where the CPU, flash, and most peripherals are halted while retaining RAM and register contents - typical current consumption is less than 10 µA at 3.3 V and 25°C, as specified in Section 5.3.2 of the H8S/2113 Group User's Manual Rev.2.00.

Is the R4F2113NLG#U0 pin-compatible with other devices in the H8S/2113 Group, such as the R4F2112NLG#U0?

Yes, the R4F2113NLG#U0 is fully pin-compatible with the R4F2112NLG#U0 and other members of the H8S/2113 Group sharing the 100-pin LQFP package. All share identical pin assignments, electrical characteristics, and peripheral mapping; only memory capacity (flash/RAM) and certain fuse-configurable features differ between variants - enabling drop-in replacement where firmware fits within the smaller memory footprint.
