Product details
Overview
R5F104ACDSP#V0 from Renesas is a 36-pin LFQFP-packaged 16-bit RL78/G14 microcontroller with 16 KB flash, 4 KB data flash, and 2.5 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (44 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), integrated 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in battery-powered industrial sensor nodes and smart metering front-ends.
For engineers reviewing the R5F104ACDSP#V0 datasheet, R5F104ACDSP#V0 pinout, R5F104ACDSP#V0 application, or R5F104ACDSP#V0 equivalent, key selection criteria include its 36-pin LFQFP-0.5 mm pitch package, -40°C to +85°C industrial temperature grade (D suffix), 16 KB code flash with self-programming and security lock, and support for background data flash rewriting at full VDD range (1.8–5.5 V).
Technical Context
The R5F104ACDSP#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a programmable Event Link Controller (ELC) enabling direct peripheral-to-peripheral event triggering without CPU intervention.
Its power management includes on-chip POR and 14-level LVD with interrupt/reset selection, while the Data Transfer Controller (DTC) supports normal, repeat, and block transfer modes activated by 19–26 interrupt sources, including chain transfer for efficient memory-to-peripheral streaming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RL78 16-bit CISC with 3-stage pipeline; enables deterministic real-time control with low gate count and minimal power per instruction. |
