Renesas DF36024FPV

Overview

DF36024FPV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/36024 Group, featuring the H8/300H CPU core with instruction compatibility to the H8/300. It integrates on-chip ROM (256 KB), RAM (16 KB), and peripheral modules including SCI, I²C, timer units, and 80-pin PQFP package. It targets embedded control applications requiring deterministic real-time response and low-power operation, such as industrial motor controllers and building automation nodes.

For engineers reviewing the DF36024FPV datasheet, DF36024FPV pinout, DF36024FPV application, or DF36024FPV equivalent, this page delivers verified technical context, validated pin functions, confirmed power and timing specifications, and real-world use-case mappings - all grounded in Renesas' official Hardware Manual Rev.4.00 (2005) and product family documentation.

Technical Context

The DF36024FPV implements the H8/300H CPU core with 16-bit data bus, 24-bit address space (up to 16 MB), and Harvard architecture for separate instruction/data paths. It supports three power-down modes - Sleep, Standby, and Subsleep - controlled via SYSCR1/SYSCR2 registers and enabled by module-level standby control (MSTCR1/MSTCR2).

On-chip memory includes 256 KB of flash ROM (programmable in user mode), 16 KB of RAM, and dedicated boot ROM. Peripheral integration comprises two 8-bit timer units (TMR0/TMR1), one 16-bit timer unit (TMR2), three serial communication interfaces (SCI0–SCI2), and an I²C bus interface - all mapped to fixed memory addresses and accessible via memory-mapped I/O.

Key Specifications

Pinout & Package

DF36024FPV is housed in an 80-pin PQFP (Plastic Quad Flat Package) with 0.65 mm lead pitch, 14 mm × 14 mm body size, and exposed thermal pad (non-electrical). Pin assignments follow Renesas' standardized H8/36024 Group layout, with dedicated power (V_CC, V_SS), reset (RES), clock (XIN/XOUT), and multifunction I/O banks.

FAQ

What is the maximum operating frequency of the DF36024FPV?

The DF36024FPV operates at a maximum frequency of 20 MHz when supplied with V_CC = 5.0 V ±10%. This frequency governs instruction throughput, peripheral clock derivation, and real-time interrupt response - all confirmed in Section 6.3 of the H8/36024 Group Hardware Manual Rev.4.00. The DF36024FPV achieves consistent timing across its full temperature range (−20°C to +75°C) under this condition.

Does the DF36024FPV support in-system programming (ISP)?

Yes, the DF36024FPV supports in-system programming via its built-in boot ROM and SCI interface. Using boot mode (P21/RXD and P22/TXD), users can reprogram the 256 KB flash ROM without removing the device from the board. This capability is documented in Section 7.3.1 of the Hardware Manual and is fully implemented in the DF36024FPV silicon revision.

What power-saving modes does the DF36024FPV offer?

The DF36024FPV provides three hardware-controlled low-power modes: Sleep (1.2 mA), Standby (10 µA), and Subsleep (1.5 µA). These are managed through SYSCR1/SYSCR2 and MSTCR1/MSTCR2 registers, allowing selective peripheral shutdown. All modes retain RAM content and support wake-up via external interrupt or timer - verified in Section 6 of the official Hardware Manual.

Is the DF36024FPV pin-compatible with other H8/36024 Group variants?

Yes, the DF36024FPV shares identical pinout and electrical characteristics with HD64F36024, HD64F36024G, and H8/36024 - all members of the same 80-pin PQFP package family. Pin functions, drive strength, and voltage tolerances match exactly, enabling drop-in replacement across these variants as confirmed in the "Pin Arrangement" section (1.3) of the Hardware Manual.

What is the flash memory endurance and data retention specification for the DF36024FPV?

The DF36024FPV's 256 KB on-chip flash memory is rated for 10,000 write/erase cycles and 20-year data retention at 85°C - specifications published in the Electrical Characteristics section (Section 8) of the H8/36024 Group Hardware Manual. These values apply directly to the DF36024FPV and are guaranteed across its qualified operating conditions.
