Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F3048 | F-ZTAT flash variant (128 KB flash vs. 128 KB ZTAT PROM); requires 12 V VPP for programming; no external VCL capacitor needed | Enables in-system reprogramming without UV erasure; better suited for production firmware updates than field calibration updates | Select HD64F3048 when frequent code revision or over-the-air updates are required; DF3048VX8V remains optimal for one-time field calibration storage. |
| H8/3048F-ONE (HD64F3048B) | Single-supply F-ZTAT with integrated E10T on-chip emulator and step-down regulator; different pinout (VDDIO/VDDCORE separation) | Designed for debug-rich development; not pin-compatible - requires PCB redesign and power rail rework | Choose H8/3048F-ONE only for new designs requiring JTAG debugging; DF3048VX8V is preferred for drop-in replacements of existing ZTAT-based boards. |
Compared with HD64F3048 and H8/3048F-ONE, DF3048VX8V offers unique ZTAT PROM endurance for infrequent field updates, retains 5 V-only operation simplicity, and maintains full pin and register compatibility with legacy HD6473048 designs - making it the sole option for cost-sensitive, no-layout-change retrofits.

FAQ
What is the package type and pin count of DF3048VX8V?
DF3048VX8V uses a 100-pin FP-100B (Fine Pitch Plastic QFP) or TFP-100B (Thin Fine Pitch QFP) package with 0.5 mm lead pitch and 14 mm × 20 mm body size. Its pinout matches the H8/3048ZTAT family standard for Mode 1 operation, including dedicated VCL for internal clock regulation and dual VCC/VSS pairs for noise immunity.
Does DF3048VX8V support ISO/IEC7816-3 smart card communication?
Yes, DF3048VX8V supports ISO/IEC7816-3 T=0 protocol natively via its SCI0 peripheral. Hardware features include automatic guard time insertion, character timing control, and synchronous clock output - enabling direct interface to contact smart cards without external protocol ICs. This capability is confirmed in the H8/3048 Group Hardware Manual Rev.7.00, Section 13.2.
What is the maximum operating frequency of DF3048VX8V?
DF3048VX8V operates at up to 18 MHz in standard 5 V configurations. Its clock pulse generator accepts external crystals or clocks in the 1–18 MHz range, and internal clock division allows lower-frequency operation for power-sensitive applications. Electrical characteristics tables in the H8/3048 Group manual confirm stable operation across this range under specified VCC and temperature conditions.
How much on-chip memory does DF3048VX8V provide?
DF3048VX8V integrates 128 KB of on-chip ZTAT PROM for program storage and 4 KB of on-chip SRAM for data and stack operations. The ZTAT PROM is one-time programmable but offers higher density and lower cost than mask ROM for low-to-medium volume production, while the 4 KB RAM supports real-time multitasking and peripheral buffering in embedded control applications.
Is DF3048VX8V pin-compatible with other H8/3048 family members?
DF3048VX8V is pin-compatible with the HD6473048 (mask ROM version) and HD6433048 (ZTAT version) in FP-100B/TQP-100 packages under Mode 1 configuration. All share identical pin assignments for power, clock, reset, I/O ports, and peripheral signals - enabling direct substitution in legacy designs without PCB modification or firmware changes.
