Product details
Overview
R5F523W8CDLN#20 from Renesas is a 32-bit RXv2 microcontroller with integrated Bluetooth 5.0 LE RF transceiver, 54 MHz operation, 512 KB flash, 64 KB SRAM, and 8 KB data flash. It features a hardware FPU (IEEE 754), 12-bit A/D and D/A converters, capacitive touch sensing (12 keys), USB 2.0 OTG, CAN, SD host interface, and TSIP-Lite encryption - designed for secure, low-power wireless IoT edge nodes.
For engineers reviewing the R5F523W8CDLN#20 datasheet, R5F523W8CDLN#20 pinout, R5F523W8CDLN#20 application, or R5F523W8CDLN#20 equivalent, this page delivers verified package mapping (83-pin LGA, PTLG0083KA-B), confirmed Bluetooth-certified RF integration, exact peripheral channel counts per package, real-time clock with battery backup, and validated alternative MCU options for wireless sensor and BLE gateway designs.
Technical Context
The R5F523W8CDLN#20 implements the RXv2 CPU core with 54 MHz max frequency, 88.56 DMIPS, and single-precision FPU - enabling deterministic real-time control and floating-point sensor fusion. Its ELC (Event Link Controller) enables interrupt-free inter-module triggering, supporting ultra-low-power operation during software standby using the LPT timer and RTC with battery backup.
It integrates a certified Bluetooth 5.0 LE subsystem including on-die RF transceiver, link layer, AES-CCM encryption engine, and dedicated 32 MHz crystal oscillator - all housed in an 83-pin LGA package with embedded PCB trace antenna and DC-DC/linear RF power supply selection. The CTSU supports both self- and mutual-capacitance touch up to 12 keys without external components.

The R5F523W8CDLN#20 is certified compliant with radio-related laws in Japan (MIC), North America (FCC/ISED), and Europe (CE RED). Certification covers the full 83-pin LGA package with its integrated PCB trace antenna and onboard 32 MHz Bluetooth oscillator - no additional RF testing is required for end-product integration.
Does the R5F523W8CDLN#20 include hardware encryption capabilities?
Yes, the R5F523W8CDLN#20 includes TSIP-Lite - a dedicated hardware security engine supporting AES-128/256 in ECB, CBC, GCM, and CMAC modes, plus true random number generation and secure key management. This enables secure boot, encrypted firmware updates, and data-at-rest protection without CPU overhead.
What are the key differences between R5F523W8CDLN#20 and R5F523W8DDLN#20?
R5F523W8DDLN#20 adds the TSIP-Lite security function while retaining the same 83-pin LGA package, integrated antenna, and Bluetooth certification as R5F523W8CDLN#20. The "D" suffix denotes inclusion of both antenna and security - making R5F523W8DDLN#20 the functional superset for applications requiring cryptographic compliance.
Can the R5F523W8CDLN#20 operate from a coin-cell battery?
Yes, the R5F523W8CDLN#20 supports operation from 1.8 V and features three low-power modes, including software standby with active LPT and RTC on VBATT. With optimized firmware, it achieves sub-1 µA sleep current - enabling multi-year operation on CR2032 batteries in touch or sensor wake-up applications.
Is the Bluetooth subsystem in R5F523W8CDLN#20 fully integrated or does it require external components?
The Bluetooth subsystem in R5F523W8CDLN#20 is fully integrated: it includes the RF transceiver, link layer, AES-CCM encryption engine, 32 MHz dedicated oscillator, and PCB trace antenna. Only passive decoupling capacitors and a 32 MHz crystal (already mounted on the 83-pin LGA package) are required - no balun, matching network, or external RF ICs needed.
