For engineers reviewing the R5F51138AGFP#1A datasheet, R5F51138AGFP#1A pinout, R5F51138AGFP#1A application, or R5F51138AGFP#1A equivalent, this page delivers verified specifications, package mapping to PLQP0100KB-A (100-pin LFQFP), functional pin roles, thermal grade (−40 to +105°C), and validated alternative MCUs for migration or sourcing continuity.
Technical Context
The R5F51138AGFP#1A implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and on-chip debugging support. It integrates an Event Link Controller (ELC) enabling direct inter-module triggering without CPU intervention and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by 44 event sources.
Its clock system includes a high-speed on-chip oscillator (32 MHz ±1% over −20 to +85°C), PLL, sub-clock (32.768 kHz), and dedicated IWDT/USB oscillators. Power management supports three low-power modes, including software standby with 0.44 µA supply current and 4.8 µs wake-up time.

FAQ
What is the maximum operating temperature specification for the R5F51138AGFP#1A?
The R5F51138AGFP#1A is qualified for operation from −40°C to +105°C, making it suitable for demanding industrial environments such as enclosed control cabinets or outdoor equipment housings where ambient temperatures exceed +85°C. This extended temperature grade distinguishes it from the D-version (−40°C to +85°C) variants like R5F51138ADFP#3A. The specification is validated across all peripherals including USB, A/D, and LCD drivers.
Does the R5F51138AGFP#1A support USB On-The-Go (OTG) functionality?
Yes, the R5F51138AGFP#1A integrates a full-featured USB 2.0 host/function/OTG module compliant with USB specification 2.0. It supports full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, isochronous transfers, Battery Charging (BC) detection, and OTG session request protocol (SRP) and host negotiation protocol (HNP). The R5F51138AGFP#1A requires no external PHY - all transceiver circuitry is embedded on-die.
How many capacitive touch channels does the R5F51138AGFP#1A support, and what is the implementation method?
The R5F51138AGFP#1A supports 12 capacitive touch sensing channels via its integrated Capacitive Touch Sensing Unit (CTSU), available exclusively on the 100-pin package variants. It implements both self-capacitance and mutual-capacitance measurement methods, with an on-chip noise canceller that actively suppresses periodic and random interference. The R5F51138AGFP#1A's CTSU operates independently of the CPU using dedicated hardware acceleration, enabling low-latency touch response with minimal firmware overhead.
What are the key differences between the R5F51138AGFP#1A and the R5F51138ADFP#3A?
The R5F51138AGFP#1A and R5F51138ADFP#3A share identical peripherals, memory sizes (512 KB flash, 64 KB SRAM), package (PLQP0100KB-A), and pinout. Their sole difference is operating temperature grade: R5F51138AGFP#1A is rated for −40°C to +105°C, while R5F51138ADFP#3A is rated for −40°C to +85°C. All electrical characteristics, timing parameters, and functional behavior are otherwise identical across the specified temperature ranges.
Is background operation (BGO) supported for data flash writes on the R5F51138AGFP#1A?
Yes, the R5F51138AGFP#1A supports Background Operation (BGO) for its 8 KB on-chip data flash. While executing code from main flash memory, the R5F51138AGFP#1A can simultaneously erase or program data flash sectors - enabling seamless firmware updates, parameter storage, or event logging without halting real-time tasks. BGO is managed via the Flash Control Module (FCM) and requires proper interrupt masking and status polling per Renesas Application Note R01AN1403.
