Product details
Overview
R5F52316CDLA#20 from Renesas is a 32-bit RXv2 core MCU operating at up to 54 MHz (88.56 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 12-bit A/D converter (24 channels), USB 2.0 full-speed host/function/OTG, and capacitive touch sensing unit - deployed in industrial HMI and consumer appliance control systems requiring real-time responsiveness and secure firmware execution.
For engineers reviewing the R5F52316CDLA#20 datasheet, R5F52316CDLA#20 pinout, R5F52316CDLA#20 application, or R5F52316CDLA#20 equivalent, this page delivers verified specifications, package mapping to TFLGA-100 (PTLG0100KA-A), validated peripheral configurations, and confirmed alternative options for migration or second-sourcing in embedded control designs.
Technical Context
The R5F52316CDLA#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip FPU compliant to IEEE 754 single-precision standard. It supports little- or big-endian data arrangement and includes memory protection unit (MPU) for runtime safety-critical partitioning.
Its clock system integrates main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), and USB-dedicated PLL enabling simultaneous 54 MHz system clock and 48 MHz USB clock. Real-time operation is sustained via RTC with calendar mode, low-power timer (LPT), and three low-power modes including software standby.

These functions are fully documented in Section 1.1 and Table 1.1 of R01DS0261EJ0120.
Is the R5F52316CDLA#20 qualified for industrial temperature range?
Yes, the R5F52316CDLA#20 is rated for the industrial temperature range of −40°C to +85°C (D version), as specified in Table 1.3 of the datasheet.
