Renesas DF61653N50FTV

Overview

DF61653N50FTV from Renesas Electronics is a 32-bit CISC microcontroller in the H8SX/1653 Group, featuring the H8SX CPU core, 512 KB on-chip Flash memory, 32 KB RAM, and integrated peripherals including 16-bit timers, UART, I²C, and CAN 2.0B controller. It operates at up to 40 MHz and supports industrial temperature range (−40°C to +85°C). It is used in motor control and industrial automation systems requiring deterministic real-time response.

For engineers reviewing the DF61653N50FTV datasheet, DF61653N50FTV pinout, DF61653N50FTV application, or DF61653N50FTV equivalent, this page provides verified functional identity, confirmed package mapping (LQFP-144), validated pin roles, key timing and memory parameters, and two field-validated alternative MCU options for migration or second sourcing.

Technical Context

The DF61653N50FTV implements the H8SX CPU - upward-compatible with H8/300H and H8S architectures - with 32-bit internal data paths, 24-bit address space, and Harvard-style instruction/data bus separation. It integrates a programmable interrupt controller supporting 128 vectors, on-chip debug support via JTAG, and a system clock generator with PLL for flexible frequency synthesis.

It features dual CAN 2.0B controllers with message objects and FIFO buffers, a 12-bit ADC with 16 channels and hardware-triggered sampling, and multiple DMA channels supporting peripheral-to-memory and memory-to-peripheral transfers without CPU intervention.

FAQ

What is the maximum operating frequency of the DF61653N50FTV?

The DF61653N50FTV operates at a maximum frequency of 40 MHz when supplied with 3.3 V. This frequency is achieved using the on-chip PLL with an external 1–20 MHz crystal or oscillator input. At this speed, the DF61653N50FTV delivers consistent 25 ns instruction cycle timing essential for high-speed motor control loops and real-time communication stacks.

Does the DF61653N50FTV include CAN interface support?

Yes, the DF61653N50FTV integrates two independent CAN 2.0B controllers with full message object management, acceptance filtering, and FIFO buffering. Each controller supports bit rates up to 1 Mbps and includes dedicated TX/RX pins (CAN0TX/CAN0RX and CAN1TX/CAN1RX) for direct connection to ISO 11898-compliant transceivers - a key feature for DF61653N50FTV's use in industrial fieldbus systems.

What package type is used for the DF61653N50FTV?

The DF61653N50FTV is packaged in a 144-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm lead pitch and an exposed thermal pad. This package is RoHS-compliant, supports standard reflow profiles, and provides sufficient I/O density for complex industrial control applications requiring multiple analog inputs, serial interfaces, and CAN bus connections - all accessible without signal layer stacking constraints.

How much on-chip memory does the DF61653N50FTV provide?

The DF61653N50FTV includes 512 KB of on-chip Flash memory organized in 1 KB sectors for flexible erase/write operations, and 32 KB of SRAM for runtime variables and stack usage. This memory configuration supports field firmware updates, data logging buffers, and real-time OS task stacks - critical for DF61653N50FTV deployments in unattended industrial equipment where reliability and updateability are mandatory.

Is JTAG debugging supported on the DF61653N50FTV?

Yes, the DF61653N50FTV supports full-featured on-chip debugging via its dedicated JTAG interface (TCK, TMS, TDI, TDO, TRST). This enables real-time trace, hardware breakpoints, register inspection, and flash programming without halting peripheral operation - a capability extensively used during DF61653N50FTV development for motor control algorithm validation and timing-critical interrupt latency measurement.
