Product details
Overview
R5F61648AD50FPV from Renesas Electronics is a 32-bit CISC microcontroller in the H8SX/1648 Group, featuring a 50 MHz maximum CPU clock, 512 KB on-chip Flash memory, and integrated peripherals including TPU, SCI, WDT, and DTC. It operates from a 3.0–3.6 V supply and targets industrial control and embedded automation systems requiring deterministic real-time response.
For engineers reviewing the R5F61648AD50FPV datasheet, R5F61648AD50FPV pinout, R5F61648AD50FPV application, or R5F61648AD50FPV equivalent, key selection criteria include its 144-pin LQFP package, 50 MHz operation with internal PLL, 512 KB Flash/32 KB RAM memory map, and support for multiple low-power modes (HALT, STOP, and WAIT) - all critical for motion control and PLC edge-node designs.
Technical Context
The R5F61648AD50FPV implements the H8SX CPU core with three operating modes (Normal, Middle, Advanced), enabling scalable performance and code compatibility across the H8SX/1600 series. It integrates a Clock Pulse Generator (CPG) supporting crystal, external clock, or internal oscillator inputs with PLL multiplication up to ×2 for 50 MHz operation.
Peripheral integration includes a 16-bit Timer Pulse Unit (TPU) with 16 channels, four Serial Communications Interfaces (SCI) supporting asynchronous and clock-synchronous modes, and a Data Transfer Controller (DTC) that offloads CPU during memory-to-peripheral transfers - reducing interrupt latency in high-speed I/O applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F61648AD60FPV | Same package and pinout; rated for 60 MHz max CPU frequency (requires higher-grade oscillator and tighter power regulation) | Suitable for higher-bandwidth control loops (e.g., >20 kHz servo update) where timing margin is critical | Select when system-level timing analysis confirms need for >50 MHz sustained throughput under worst-case voltage/temperature |
| R5F61648AD50FP | Identical electrical specs and peripherals; differs only in package marking (FP vs FPV) - FP denotes lead-free, halogen-free variant per J-STD-609 | No functional difference; FP meets stricter environmental compliance for EU medical or consumer equipment | Choose FP for RoHS+REACH-regulated end products where material declarations are audited |

This feature ensures firmware integrity during program execution and field updates, especially in electrically noisy industrial environments where bit flips may occur - a capability confirmed in the device's hardware manual section 1.1.1 and memory specification tables.
Which communication interfaces are integrated into the R5F61648AD50FPV?
The R5F61648AD50FPV integrates four independent Serial Communications Interfaces (SCI), each supporting asynchronous (UART) and clock-synchronous (SPI-like) modes, plus additional peripherals including I²C-compatible bus controller (BSC), programmable pulse generator (PPG), and data transfer controller (DTC). These interfaces are documented in the H8SX/1648 Group Hardware Manual sections 1.4.3 and 12.1–12.4.
What power-saving modes does the R5F61648AD50FPV support?
The R5F61648AD50FPV supports three low-power operating modes: HALT (CPU clock stopped, peripherals active), STOP (all clocks halted, RAM retention enabled), and WAIT (CPU halted, selected peripherals remain clocked). Each mode is software-configurable via the System Control Register (SYSCR) and detailed in section 5.3 of the H8SX/1648 Group Hardware Manual Rev. 2.00.
Is the R5F61648AD50FPV pin-compatible with other devices in the H8SX/1648 Group?
Yes, the R5F61648AD50FPV shares identical pin assignment and electrical characteristics with other members of the H8SX/1648 Group, including R5F61648AD60FPV and R5F61648AD50FP, as defined in section 1.4.1 "Pin Assignments" of the H8SX/1648 Group Hardware Manual.
