Renesas D73048SF16V

Overview

D73048SF16V from Hitachi is an H8/3048 Series 16-bit single-chip microcontroller with 128 KB on-chip ROM (PROM), 4 KB RAM, 18 MHz max CPU clock, 10-bit 8-channel A/D converter, and 8-bit 2-channel D/A converter. It integrates DMA controller, dual SCI interfaces, five 16-bit timer channels, programmable timing pattern controller, and watchdog timer - deployed in industrial motor control systems requiring deterministic real-time I/O handling and analog feedback loops.

For engineers reviewing the D73048SF16V datasheet, D73048SF16V pinout, D73048SF16V application, or D73048SF16V equivalent, key selection criteria include ZTAT™ zero-turnaround-time PROM execution, 100-pin TQFP package compatibility, 18 MHz real-time interrupt latency, integrated DRAM refresh controller for external memory expansion, and dual smart-card-capable serial interfaces.

Technical Context

The D73048SF16V implements the H8/300H CPU core with 32-bit internal data paths, sixteen 16-bit general-purpose registers (expandable to eight 32-bit or sixteen 8-bit registers), and a 16-Mbyte linear address space. It supports seven operating modes including Single-Chip Mode (Mode 7) and multiple expanded bus modes with configurable 8-/16-bit data width and wait-state control.

Its peripheral set includes a 4-channel DMA controller supporting memory-memory and memory-I/O transfers, a 16-bit Integrated Timer Unit (ITU) delivering up to 12 pulse outputs at 55.6 ns resolution, and a Programmable Timing Pattern Controller (TPC) synchronized to ITU timers for precise multi-phase waveform generation - all managed via dedicated on-chip bus controller and refresh controller for DRAM/PSRAM interfacing.

Equivalent & Alternatives

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

Compared with the D73048SF16V, the H8S/2357 offers higher clock speed and CAN capability but sacrifices ZTAT™ execution and smart card support, while the SH7049 provides superior compute performance at the cost of increased BOM complexity and loss of integrated analog peripherals.

Availability

D73048SF16V is available at Aetrix Electronics and suitable for industrial motor drives, PLC I/O modules, energy metering front-ends, and medical infusion pump controllers requiring stable component supply across extended product lifecycles.

Supply support for D73048SF16V 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

Hitachi Ltd. (now part of Renesas Electronics Corporation) was a Japanese multinational conglomerate specializing in industrial automation, power systems, and semiconductor design - particularly known for high-reliability microcontrollers for factory and infrastructure applications.

The H8/3048 Series was designed for deterministic real-time control in resource-constrained industrial environments, emphasizing integrated analog peripherals, low-latency interrupt response, and robust external memory interfacing - not general-purpose computing.

FAQ

What is the maximum operating frequency of the D73048SF16V?

The D73048SF16V supports a maximum oscillator frequency of 18 MHz, enabling its H8/300H CPU core to execute register-register arithmetic operations in 111 ns. This frequency is specified under commercial temperature range (0°C to +70°C) with VCC = 5.0 V ±10%. The D73048SF16V does not support frequency scaling or PLL-based clock multiplication.

Does the D73048SF16V include on-chip flash or mask ROM?

No - the D73048SF16V features user-programmable PROM (ZTAT™ type), not flash or mask ROM. This PROM is one-time programmable and supports zero-wait-state execution. The 'SF' suffix in D73048SF16V explicitly denotes PROM-based configuration, distinguishing it from mask-ROM variants like D73048MF16V.

Can the D73048SF16V generate complementary PWM signals with dead-time control?

Yes - the D73048SF16V combines its 16-bit Integrated Timer Unit (ITU) and Programmable Timing Pattern Controller (TPC) to generate up to three complementary PWM waveforms with non-overlap intervals programmable in TPC registers. This capability is confirmed in Section 1 and Section 6.5 of the H8/3048 Series Hardware Manual.

Is the D73048SF16V pin-compatible with other H8/3048 Series variants like D73047 or D73044?

Yes - all H8/3048 Series devices, including D73048SF16V, D73047, and D73044, share identical 100-pin TQFP-100B packaging and pinout. Differences are limited to on-chip ROM/RAM sizes and PROM vs. mask-ROM implementation; peripheral functionality and signal mapping remain fully consistent across the series.

What development tools are officially supported for the D73048SF16V?

Hitachi provided the E7000 Series real-time emulator for the D73048SF16V, compatible with UNIX workstations on LAN. Software toolchain included the H8/300H C compiler and ITRON-compliant real-time OS. No official JTAG or SWD debug interface exists - debugging relies on the dedicated E7000 probe connecting to the RESO, ø, and BREQ/BACK pins.
