It targets battery-powered LCD display systems such as smart meters, thermostats, and industrial HMI panels.
For engineers reviewing the R5F10RLAGFA#V0 datasheet, R5F10RLAGFA#V0 pinout, R5F10RLAGFA#V0 application, or R5F10RLAGFA#V0 equivalent, this page delivers verified technical context, package-accurate pin definitions, real-world use cases for LCD-based embedded control, and validated alternative options aligned with industrial temperature grade (−40°C to +105°C) and functional safety requirements per IEC/UL 60730.
Technical Context
The R5F10RLAGFA#V0 implements the RL78 CPU core delivering 31 DMIPS at 24 MHz, with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 clock cycles. It integrates dual-clock domains: high-speed on-chip oscillator (24 MHz ±1% over 1.8–5.5 V and −20°C to +85°C) and low-frequency subsystem clock (32.768 kHz crystal support).
Its peripheral set includes an 8-channel timer array unit, 10-bit ADC with 10 channels and 2.1 µs conversion time, UART/I²C/CSI interfaces, DMA controller (2 channels), and hardware CRC engine. Safety features include RAM parity check, SFR write protection, illegal memory access detection, and ADC self-test - all certified for IEC/UL 60730 compliance.

FAQ
What is the maximum operating frequency and power consumption of the R5F10RLAGFA#V0?
The R5F10RLAGFA#V0 operates at up to 24 MHz using its high-speed on-chip oscillator (±1% accuracy), delivering 31 DMIPS. In active mode, it consumes 62.5 µA/MHz; in halt mode with RTC and LVD enabled, it draws just 0.64 µA - enabling decade-long battery life in LCD applications. The device also supports snooze mode for low-latency wake-up from deep sleep.
Does the R5F10RLAGFA#V0 support IEC 60730 functional safety compliance?
Yes, the R5F10RLAGFA#V0 includes hardware-level safety features required for Class B compliance per IEC/UL 60730: flash memory CRC calculation, RAM parity error detection, SFR write protection, illegal memory access detection, clock frequency monitoring, and ADC self-test. These are implemented in silicon and documented in Renesas' safety manual R01UH0497EJ0200.
What LCD configurations does the R5F10RLAGFA#V0 support, and how is contrast adjusted?
The R5F10RLAGFA#V0 supports up to 39 segment × 4 common or 35 segment × 8 common LCD drive, with selectable bias methods: capacitor split, internal voltage boost, or external resistor division. Contrast is digitally adjustable in 16 steps via dedicated registers, and blinking is supported per segment or group - all managed by the on-chip LCD controller without CPU intervention.
What are the key differences between R5F10RLAGFA#V0 and R5F10RJCGFA#V0?
R5F10RLAGFA#V0 is a 64-pin LFQFP with 58 total I/O+LCD pins and support for 39 seg × 4 com LCD drive, while R5F10RJCGFA#V0 is a 52-pin LQFP with 48 total I/O+LCD pins and 30 seg × 8 com maximum. Both share 32 KB flash, 2 KB data flash, −40°C to +105°C rating, and identical safety/peripheral sets - making R5F10RJCGFA#V0 a footprint-reduced alternative for less complex displays.
Can the R5F10RLAGFA#V0 operate from a single 1.6 V supply, and what analog features are available at that voltage?
Yes, the R5F10RLAGFA#V0 operates across 1.6 V to 5.5 V. At 1.6 V, the 10-bit ADC remains fully functional with 10 channels and 2.1 µs conversion time, using the internal 1.45 V reference. The on-chip temperature sensor, LVD (with 14 threshold options), and real-time clock (with 32.768 kHz crystal support) also operate reliably - enabling robust sensing in low-voltage battery systems.
