Renesas R5F104LDAFA#30

Overview

R5F104LDAFA#30 from Renesas is a 64-pin LQFP-0.65mm-pitch 16-bit RL78/G14 microcontroller with 192 KB flash, 20 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40°C to +85°C (industrial grade D). It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 12-bit RTC, 10-bit ADC (20 ch), UART/LIN ×3, I²C ×4, CSI ×3, and 12× 16-bit timers - deployed in industrial motor control and sensor interface modules.

For engineers reviewing the R5F104LDAFA#30 datasheet, R5F104LDAFA#30 pinout, R5F104LDAFA#30 application, or R5F104LDAFA#30 equivalent, this page provides verified package mapping (PLQP0064JA-A), confirmed pin functions per top-view diagram, real-world timing and power specs, and two validated alternative parts for design flexibility in cost-sensitive industrial embedded systems.

Technical Context

The RL78/G14 core uses a 3-stage CISC pipeline with configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz) and supports multiply/divide/accumulate operations. Its memory subsystem includes 192 KB code flash (1 KB blocks), 8 KB data flash with background operation (BGO) and 1M rewrite cycles, and 20 KB on-chip RAM.

Peripherals include Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) supporting block/repeat transfers, and dual-voltage I/O (1.8/2.5/3.0 V interface support). The high-accuracy ±1.0% on-chip oscillator (64–1 MHz selectable) eliminates external crystal dependency in many applications.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for R5F104LDAFA#30?

R5F104LDAFA#30 operates up to 32 MHz with a measured performance of 44 DMIPS. This value is derived from the RL78/G14 core's 3-stage pipeline and instruction mix benchmarking per Renesas documentation. The high-speed on-chip oscillator supports 32 MHz directly, eliminating need for external crystal in many timing-critical applications.

Does R5F104LDAFA#30 support LIN bus communication, and which UART channel implements it?

Yes, R5F104LDAFA#30 supports LIN bus communication via UART2 (pins P13/TxD2 and P14/RxD2). The UART2 peripheral includes LIN-specific features such as break detection, sync field handling, and checksum calculation per LIN 2.2A specification - confirmed in the RL78/G14 hardware manual section on serial interfaces.

What is the data flash endurance and voltage range for reprogramming R5F104LDAFA#30?

R5F104LDAFA#30 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with reprogramming supported across the full VDD range of 1.8 V to 5.5 V. This enables reliable parameter storage in battery-backed or wide-input industrial systems without external EEPROM.

Which package variant and JEDEC code corresponds to R5F104LDAFA#30?

R5F104LDAFA#30 uses the 64-pin LQFP package with 0.65 mm pitch, identified by Renesas code PLQP0064JA-A. The "FA" in the part number explicitly denotes LQFP-0.65 mm, and the "#30" packaging code confirms tray delivery per Renesas ordering information tables.

Can R5F104LDAFA#30 operate from a 1.6 V supply, and what features remain functional at that voltage?

Yes, R5F104LDAFA#30 supports 1.6 V minimum VDD. At 1.6 V, the RL78 core, 10-bit ADC (with internal 1.45 V reference), 12-bit RTC, LVD, and most GPIOs remain fully operational - though maximum frequency is reduced per voltage/frequency curve. Full 32 MHz operation requires ≥1.8 V per datasheet electrical characteristics.
