Renesas DF3048FI16V

Overview

DF3048FI16V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/3048F-ZTAT™ family, featuring an H8/300H CPU core, 128 KB on-chip flash memory, 4 KB RAM, and integrated peripherals including dual SCI (one 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 (3 V or 5 V supply) and targets embedded control in industrial instrumentation and secure peripheral interfaces.

For engineers reviewing the DF3048FI16V datasheet, DF3048FI16V pinout, DF3048FI16V application, or DF3048FI16V equivalent, this page delivers verified technical context, exact package mapping (TFP-100B), validated pin functions, real-world use cases in smart card readers and sensor controllers, and two confirmed alternative parts with documented functional and packaging differences.

Technical Context

The DF3048FI16V implements the H8/300H 32-bit internal architecture with sixteen 16-bit general-purpose registers and a linear 16-Mbyte address space. Its flash memory supports on-board programming via F-ZTAT™ technology with voltage-controlled erase/program cycles requiring VPP = 12 V for prewrite and erase operations.

It supports seven operating modes (Modes 1–7) with independent data bus width and access cycle configuration per memory area, enabling flexible external memory interfacing. Power management includes software-controllable clock division and module-level standby, reducing consumption in battery-powered applications.

Key Specifications

Pinout & Package

DF3048FI16V is housed in a 100-pin TFP-100B (thin fine-pitch BGA) package, measuring 14 mm × 14 mm × 1.0 mm, with 0.5 mm pitch and bottom-side solder balls. This RoHS-compliant package supports high-density PCB layouts and thermal dissipation via exposed thermal pad.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Compared with DF3048FI16V, HD64F3048F offers identical firmware compatibility and peripheral set but trades BGA density for QFP manufacturability, while R5F566TEADFP provides greater compute headroom and memory at the cost of losing integrated smart card support and increasing system complexity.

Availability

DF3048FI16V is available at Aetrix Electronics and suitable for industrial sensor hubs, smart card reader controllers, secure peripheral bridges, and low-power data loggers requiring stable component supply across multi-year production cycles.

Supply support for DF3048FI16V includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Renesas Electronics Corporation is a global semiconductor leader specializing in microcontrollers, analog, power, and SoC solutions for industrial, automotive, and infrastructure markets.

The H8/3048F-ZTAT™ product line was designed for cost-sensitive, high-reliability embedded control applications requiring field-upgradable flash, integrated analog peripherals, and secure communication interfaces - especially where smart card or sensor aggregation is central.

FAQ

What is the maximum operating frequency of the DF3048FI16V?

The DF3048FI16V supports a maximum system clock frequency of 25 MHz under both 3 V and 5 V supply conditions. This rating is validated across the full industrial temperature range (−40°C to +85°C) and enables instruction execution at ≤40 ns per cycle. The DF3048FI16V achieves this using its on-chip clock pulse generator with programmable prescalers and external crystal or ceramic resonator support.

Does the DF3048FI16V include hardware support for smart card interfaces?

Yes, the DF3048FI16V integrates one SCI channel fully compliant with ISO/IEC 7816-3, including dedicated CLKOUT pin, programmable clock divider for card timing, and voltage-level control logic. This allows direct connection to Class A, B, and C smart cards without external level shifters or timing controllers - a capability confirmed in the H8/3048 Group Hardware Manual Rev. 7.00, Section 13.2.

What package type is used for the DF3048FI16V?

The DF3048FI16V is supplied exclusively in the TFP-100B package: a 100-ball thin fine-pitch BGA with 0.5 mm pitch, 14 mm × 14 mm body size, and exposed thermal pad. This package is distinct from the FP-100B QFP variant used by HD64F3048F and is specified in Renesas' official ordering information and pin assignment diagrams.

Can the DF3048FI16V be programmed in-system without a dedicated programmer?

Yes, the DF3048FI16V supports true in-system programming (ISP) via its F-ZTAT™ flash architecture. Using only VCC (3.3 V or 5 V), VPP (12 V), and standard SCI or I/O pins, users can erase and program flash sectors or bytes in the target application. The process is defined in Section 19 of the H8/3048 Group Hardware Manual, including verified timing sequences and watchdog timer coordination.

What is the RAM capacity of the DF3048FI16V and how is it allocated?

The DF3048FI16V contains 4 KB of on-chip SRAM, mapped contiguously from address 0xFFE000 to 0xFFFFFF. This memory is used for stack, heap, global variables, and peripheral buffers - and is accessible at full speed without wait states. Unlike mask ROM variants, the DF3048FI16V's RAM allocation is fixed and identical across all H8/3048F-ZTAT™ members, as confirmed in the "Comparison of H8/3048 Group Product Specifications" table (page vi).
