Product details
Overview
HD64F3694GFPV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Tiny Series, featuring an H8/300H CPU core with H8/300 instruction set compatibility, 64 KB on-chip ROM, 4 KB RAM, and integrated peripherals including UART, timer/counters, and I/O ports. It operates at up to 20 MHz and targets embedded control in industrial equipment and consumer appliances.
For engineers reviewing the HD64F3694GFPV datasheet, HD64F3694GFPV pinout, HD64F3694GFPV application, or HD64F3694GFPV equivalent, key selection criteria include its 100-pin LQFP package, 3.3 V/5 V dual-voltage operation support, on-chip flash programming capability, and low-power sleep/standby modes for energy-constrained systems.
Technical Context
The HD64F3694GFPV implements the H8/300H CPU architecture with 24-bit address space, supporting both 8-bit and 16-bit data operations. Its memory map includes dedicated areas for on-chip ROM (0x000000–0x00FFFF), RAM (0x010000–0x010FFF), and peripheral registers (0x011000–0x011FFF).
It integrates a system clock generator with crystal, ceramic resonator, or external clock input options; a subclock generator for 32.768 kHz RTC support; and three power-down modes-Sleep, Standby, and Subsleep-with configurable module-level standby control via MSTCR1 register.

| Supply Voltage | 3.3 V ±0.3 V or 5.0 V ±10 % operation, with separate VCC and VSS pins per port group for noise isolation |
Pinout & Package
HD64F3694GFPV is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are defined across 10 I/O ports (P0–P9), clock inputs (XIN/XOUT, SUBXIN/SUBXOUT), reset (RES), interrupt (IRQ0–IRQ7, NMI), and power/ground rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P07 | Port 0 bidirectional I/O | 8-bit parallel interface; P00–P03 double-function as UART0 TXD/RXD/CTS/RTS; default high-impedance on reset |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3687GFPV | Same H8/300H core, 32 KB ROM, 2 KB RAM, identical 100-pin LQFP package and pinout | Lower memory capacity suits simpler control tasks; lacks UART1 and one timer channel | Select when firmware size ≤30 KB and dual UART not required; reduces BOM cost without layout change |
| R5F100PLAFB | RL78/G13 16-bit core, 128 KB flash, 12 KB RAM, 100-pin LQFP but different pin assignment and voltage range (1.6–5.5 V) | Higher integration (12-bit ADC, DMA, LIN), newer toolchain support, but requires PCB redesign | Choose for new designs needing enhanced analog integration and long-term roadmap support; not drop-in compatible |
Compared with HD64F3687GFPV, HD64F3694GFPV provides double the ROM and RAM plus extra peripherals for complex firmware; versus R5F100PLAFB, it offers proven industrial reliability and legacy toolchain continuity but lacks modern low-power features and analog integration.

FAQ
What is the maximum operating frequency of the HD64F3694GFPV?
The HD64F3694GFPV supports a maximum system clock frequency of 20 MHz when driven by an external crystal or ceramic resonator connected to the XIN/XOUT pins. This frequency is achievable across the full industrial temperature range (–40°C to +85°C) under specified 3.3 V or 5 V supply conditions, and enables instruction execution at 20 MIPS for time-critical control loops.
Does the HD64F3694GFPV support in-system programming of its on-chip flash memory?
Yes, the HD64F3694GFPV supports on-board programming (OBP) of its 64 KB flash memory via UART0 using the built-in boot mode. When the mode pins are set to initiate boot mode at power-on, the device executes internal bootloader code that accepts Intel HEX-formatted firmware images over serial interface, eliminating need for external programming hardware.
What power-saving modes are available on the HD64F3694GFPV and how do they differ?
The HD64F3694GFPV offers Sleep, Standby, and Subsleep modes. Sleep halts the CPU while keeping peripherals active; Standby stops both CPU and most peripherals but retains RAM content; Subsleep disables all clocks except the 32.768 kHz subclock domain, reducing current to 1.2 µA while enabling periodic wake-up via subclock alarm - ideal for battery-operated sensor nodes.
Is the HD64F3694GFPV pin-compatible with other members of the H8/3694 Group?
Yes, the HD64F3694GFPV shares identical 100-pin LQFP package and pinout with other H8/3694 variants including HD64F3694, HD64F3694G, and HD64N3694G. This allows direct substitution within the same family for memory or feature scaling - for example, upgrading from HD64F3694GFPV (64 KB ROM) to HD64F3694GFPV-XXX with larger ROM variant requires no PCB change.
What development tools are officially supported for the HD64F3694GFPV?
Renesas officially supports the E8 emulator for HD64F3694GFPV hardware debugging, along with the High-Performance Embedded Workshop (HEW) IDE and the H8/300H C/C++ compiler (document number REJ10B0058). The hardware manual (Rev.5.00, 2005) and H8/300H Software Manual (REJ09B0213) provide complete register mapping and instruction set documentation required for bare-metal development of HD64F3694GFPV firmware.
