Product details
Overview
DF3048VFI8V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/3048 Group, featuring an H8/300H CPU core, 128 KB on-chip flash memory, 4 KB RAM, and integrated peripherals including dual SCI channels (one supporting ISO/IEC 7816-3 smart card interface), 16-bit ITU timer, programmable TPC, WDT, A/D and D/A converters, DMAC, and I/O ports. It operates at up to 25 MHz on 3 V or 5 V supply and targets embedded control applications requiring flexible firmware updates.
For engineers reviewing the DF3048VFI8V datasheet, DF3048VFI8V pinout, DF3048VFI8V application, or DF3048VFI8V equivalent, this page provides verified technical context, package mapping to FP-100B/TDP-100B, functional pin assignments, real-world use cases in industrial HMI and smart card terminals, and two validated alternative microcontrollers with documented differences in memory type and power architecture.
Technical Context
The DF3048VFI8V implements the H8/300H CPU core with a 32-bit internal architecture, sixteen 16-bit general-purpose registers, and linear 16-Mbyte address space. Its flash memory supports in-system programming via on-chip FLMCR register control with programmable timing and watchdog-assisted write/erase sequences.
It features dual power domains: VCC for logic and VPP (12 V) for flash programming, with dedicated VPPE bit control and prewrite verification flow. The device supports seven operating modes (Modes 1–7), enabling independent configuration of data bus width (8/16-bit) and address space per memory area for heterogeneous peripheral interfacing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3048F | Same H8/3048F core and 128 KB flash, but uses dual power supply (VCC + VDD) and lacks integrated step-down regulator; requires external 12 V VPP | Targeted at systems with existing 12 V rails and discrete power management; not suitable for single-supply battery-powered designs | Select HD64F3048F when board already provides 12 V and separate analog/digital supplies; DF3048VFI8V preferred for compact single-rail designs. |
| H8/3048F-ONE (HD64F3048B) | Single-supply variant with integrated step-down regulator, E10T on-chip emulator, and identical 128 KB flash - but no VPP pin or VPPE control | Optimized for debug-rich development environments and production units requiring JTAG-based firmware update; lacks field-programmable VPP path | Choose H8/3048F-ONE for prototyping and production where JTAG programming suffices; DF3048VFI8V retains flexibility for 12 V-based field updates without debugger presence. |
Compared with HD64F3048F and H8/3048F-ONE, DF3048VFI8V uniquely combines single-supply operation with dedicated 12 V VPP programming capability - enabling both simplified power design and standalone field firmware updates without external programmers or JTAG infrastructure.

FAQ
What is the maximum operating frequency of the DF3048VFI8V and under what conditions?
The DF3048VFI8V supports a maximum clock rate of 25 MHz when operated at either 3 V or 5 V supply voltage. This rating is confirmed in Section 22 (Electrical Characteristics) of the H8/3048 Group Hardware Manual Rev. 7.00. The device achieves this speed using its on-chip clock pulse generator with external crystal (1–25 MHz) or external clock input. DF3048VFI8V maintains full functionality across its specified temperature range (−40°C to +85°C) at this frequency, provided VCC and VPP meet datasheet tolerances.
Does the DF3048VFI8V support in-system programming of its flash memory, and what voltage is required?
Yes, the DF3048VFI8V supports full in-system programming of its 128 KB on-chip flash memory. Programming and erasure require a dedicated 12 V supply applied to the VPP pin (pin 20), controlled via the VPPE pin (pin 19). The flash operation sequence - including prewrite, program, and verify steps - is managed through the FLMCR register with watchdog timer assistance. DF3048VFI8V does not support 3.3 V or 5 V-only flash programming; 12 V VPP is mandatory per Renesas' F-ZTAT™ specification.
Which serial interface on the DF3048VFI8V supports ISO/IEC 7816-3, and what pins are used?
SCI0 on the DF3048VFI8V supports the ISO/IEC 7816-3 smart card interface. It uses pins 58 (SCIO_CLK), 59 (SCI0_TXD), and 60 (SCI0_RXD) for clock output, transmit, and receive respectively. The hardware implements mandatory smart card timing parameters including clock frequency control (1–5 MHz), reset assertion, guard time, and character timing - all configured via SCOCR and SCR registers. DF3048VFI8V's SCI0 is functionally distinct from SCI1, which lacks smart card-specific features.
What are the power supply requirements for the DF3048VFI8V during normal operation versus flash programming?
During normal operation, DF3048VFI8V requires only a single VCC supply (3 V or 5 V) and associated VSS grounds. For flash programming or erasure, an additional 12 V supply must be applied to the VPP pin (pin 20), enabled by asserting VPPE (pin 19) high. The 12 V VPP is disconnected during normal execution to prevent latch-up or leakage. DF3048VFI8V contains no internal charge pump; external 12 V generation and routing are mandatory per Renesas' flash programming flowcharts in Section 19 of the Hardware Manual.
How many operating modes does the DF3048VFI8V support, and how do they affect memory interfacing?
The DF3048VFI8V supports seven distinct operating modes (Modes 1–7), selected via the MDCR register. Each mode defines data bus width (8-bit or 16-bit) and address space size (1 MB to 16 MB), allowing independent configuration per memory area. This enables direct interfacing to diverse peripherals - e.g., 16-bit LCD controllers in Area 0 and 8-bit EEPROMs in Area 1 - without external bus transceivers or address latches. DF3048VFI8V's mode flexibility reduces PCB complexity and improves timing margin predictability in mixed-bus systems.
