Product details
Overview
R5F104CDALA#U0 from Renesas is a 36-pin WFLGA-packaged RL78/G14 16-bit microcontroller with 48 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (44 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes, integrated RTC, 10-bit ADC (16 channels), and UART/I²C/CSI interfaces for industrial sensor control and battery-powered HMI applications.
For engineers reviewing the R5F104CDALA#U0 datasheet, R5F104CDALA#U0 pinout, R5F104CDALA#U0 application, or R5F104CDALA#U0 equivalent, key selection criteria include its 36-pin WFLGA (4 × 4 mm, 0.5 mm pitch) footprint, -40°C to +105°C industrial temperature grade (G), 48 KB code flash with self-programming support, and hardware-peripheral event linking via ELC for deterministic real-time response in resource-constrained embedded systems.
Technical Context
The R5F104CDALA#U0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a Data Transfer Controller (DTC) supporting normal/repeat/block transfer modes triggered by 19–26 event sources linked via Event Link Controller (ELC).
Its analog subsystem includes an 8/10-bit ADC with 16 input channels, internal 1.45 V reference and temperature sensor, plus an 8-bit DAC with real-time output capability. Power management features HALT mode (66 µA/MHz), STOP mode (0.60 µA with RTC+LVD active), and on-chip LVD with 14 selectable voltage thresholds.
