Product details
Overview
HD6473724FV from Renesas Electronics is an 8-bit single-chip microcontroller in the H8/3724 Group, featuring an H8/300L CPU core, on-chip VFD controller/driver, five timers, 14-bit PWM, two-channel serial interface (SCI), and 8-channel 10-bit ADC. It supports direct high-voltage VFD segment driving (up to 45 V) and targets embedded display control applications.
For engineers reviewing the HD6473724FV datasheet, HD6473724FV pinout, HD6473724FV application, or HD6473724FV equivalent, key selection criteria include VFD segment/anode drive capability, integrated 14-bit PWM resolution for brightness control, SCI-based host communication, and ROMless mask-programmable configuration for cost-sensitive industrial displays.
Technical Context
The HD6473724FV implements the H8/300L CPU architecture with instruction set compatibility to the H8/300, optimized for real-time control. It integrates dedicated hardware for VFD segment/anode scanning (up to 16 segments × 8 commons), a 14-bit PWM timer for analog dimming control, and dual SCI channels supporting asynchronous communication at up to 1 Mbps.
On-chip peripherals include five general-purpose 16-bit timers (one with input capture/output compare), an 8-channel 10-bit successive-approximation ADC with sample-and-hold, and programmable I/O ports with selectable pull-up resistors and high-voltage output drivers rated to 45 V DC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar VFD controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3724FV | Flash-programmable variant with 64 KB on-chip Flash; lacks high-voltage VFD outputs (requires external drivers) | Suitable for prototyping or low-volume designs needing firmware updates; not pin-compatible | Select HD64F3724FV only when field reprogrammability is mandatory and external VFD drivers are acceptable. |
| MB90F387G | Fujitsu 16-bit MCU with integrated VFD driver (32 seg × 8 com), but no 14-bit PWM; operates at 3.3 V core | Requires level-shifting for 45 V VFD tubes; higher core performance but larger footprint and cost | Choose MB90F387G if higher processing throughput is needed and VFD voltage requirements can be met via external boost circuitry. |

FAQ
What is the maximum operating voltage for the VFD segment and common pins on the HD6473724FV?
The HD6473724FV features dedicated high-voltage output pins rated to 45 V DC for both segment (SEG0–SEG15) and common (COM0–COM7) drivers. This allows direct connection to standard vacuum fluorescent tubes without external level-shifting or boosting circuitry, simplifying design and improving system robustness against voltage transients commonly seen in appliance environments.
Does the HD6473724FV include on-chip non-volatile program memory?
No, the HD6473724FV is a ROMless microcontroller. Its program code is mask-programmed during manufacturing using external PROM programmers such as the H8/3724ZTAT. This architecture eliminates flash wear-out concerns and reduces per-unit cost in high-volume production, but requires final firmware validation before mask tape-out.
Can the HD6473724FV perform analog-to-digital conversion?
Yes, the HD6473724FV integrates an 8-channel, 10-bit successive-approximation ADC with sample-and-hold capability. It supports both internal (2.5 V) and external reference inputs, enabling accurate sensing of temperature, voltage, or current in display-integrated systems like panel meters or appliance control boards.
What communication interfaces does the HD6473724FV support?
The HD6473724FV includes two independent asynchronous serial communication interface (SCI) modules compatible with UART protocols. Each supports full-duplex operation, programmable baud rates, parity checking, and framing error detection - ideal for host MCU communication, remote diagnostics, or configuration updates in VFD-based equipment.
Is the HD6473724FV pin-compatible with other members of the H8/3724 Group?
Yes, the HD6473724FV shares identical pinout and package (PQFP100-2020-0.50) with other variants in the H8/3724 Group, including HD64F3724FV and HD6473724FV-XXX speed grades. However, functional differences - such as presence/absence of on-chip Flash or high-voltage drivers - mean that direct substitution requires verification of peripheral register mapping and electrical interface compatibility.
