Product details
Overview
HD6477042AVF16V from Renesas Electronics is a 32-bit RISC microcontroller in the SH7042 group, featuring an SH-2 CPU core, 128 kB on-chip mask ROM, 16-bit external bus interface, and integrated peripherals including A/D converter (±4 LSB accuracy), SCI serial interface, timers, and interrupt controller. It operates at up to 28 MHz with 5 V supply and targets real-time embedded control applications requiring deterministic timing and compact system integration.
For engineers reviewing the HD6477042AVF16V datasheet, HD6477042AVF16V pinout, HD6477042AVF16V application, or HD6477042AVF16V equivalent, this page delivers verified technical context, package mapping to QFP2020-112, confirmed DC/AC electrical characteristics, validated peripheral timing, and two documented alternative part numbers for design continuity planning.
Technical Context
The HD6477042AVF16V implements the SH-2 RISC architecture with single-cycle instruction execution for high throughput, supported by a 1-kbyte on-chip cache to accelerate external memory access. Its 16-bit external bus width enables efficient interfacing with standard SRAM, DRAM, and peripheral LSIs without glue logic.
It integrates a 8-channel 10-bit A/D converter with ±4 LSB integral nonlinearity, dual SCI modules supporting asynchronous and clocked synchronous modes, and a multifunction timer pulse unit (MTU) with complementary PWM capability - all operating under a single 5 V supply with guaranteed functionality from –20°C to +75°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit RISC microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD6437042AVF16 | Same SH-2 core and QFP2020-112 package, but with 64 kB mask ROM and identical 16-bit bus/A/D specs | Lower code density limits firmware complexity; suitable for simpler control tasks with <64 kB footprint | Select when application firmware fits within 64 kB and cost reduction is prioritized over future feature expansion |
| HD6477042AF28 | Same 128 kB mask ROM and peripherals, but rated for 28 MHz max frequency and 5 V only (no 3.3 V option) | Higher clock rate enables faster computation loops; lacks 3.3 V compatibility for mixed-voltage systems | Choose when maximum processing throughput is required and system power rails are strictly 5 V |
Compared with HD6477042AVF16V, HD6437042AVF16 offers reduced memory at lower cost for less complex firmware, while HD6477042AF28 trades 3.3 V flexibility for higher clock speed - both retain identical peripheral sets and pinout, enabling layout reuse where voltage or memory constraints permit.

FAQ
What is the maximum operating frequency of the HD6477042AVF16V?
The HD6477042AVF16V is rated for a maximum operating frequency of 16 MHz under 5 V supply conditions. This specification is confirmed in the "Notes on the SH7040 Series Specifications" table, where HD6477042AVF16 is explicitly listed with 16 MHz as its operational clock limit - distinct from the 28 MHz variant HD6477042F28. The HD6477042AVF16V must not be operated above 16 MHz to ensure compliance with timing margins and DC characteristics.
Does the HD6477042AVF16V support in-system programming?
No, the HD6477042AVF16V does not support in-system programming. It contains 128 kB of mask ROM, which is factory-programmed during wafer fabrication and cannot be modified post-manufacture. Unlike flash-based variants such as HD64F7044F28, the HD6477042AVF16V requires pre-programmed firmware and offers no software-based reprogramming capability - making it suitable for fixed-function, high-volume applications where code stability is critical.
What is the A/D converter resolution and accuracy of the HD6477042AVF16V?
The HD6477042AVF16V features an 8-channel, 10-bit A/D converter with ±4 LSB integral nonlinearity (INL) and offset error, classified as "Mid-Speed" in the specification tables. This accuracy level is confirmed for the "A mask" version operating at 16 MHz, and applies directly to the HD6477042AVF16V per the "SH7042" row in the specifications summary. The converter uses AVcc/AVss as reference and requires external RC filtering per Figure 15.14 for optimal noise rejection.
Which package type is used for the HD6477042AVF16V?
The HD6477042AVF16V is packaged in a QFP2020-112 - a 112-pin plastic quad flat package with 20 mm × 20 mm body size and 0.65 mm lead pitch. Documentation explicitly states "QFP2020-112" for the SH7042 variant with VF16 suffix, and notes copper lead material usage. This package is surface-mount compatible and aligns with JEDEC MS-026 standards for automated PCB assembly.
Is the HD6477042AVF16V pin-compatible with other SH7042 variants?
Yes, the HD6477042AVF16V shares identical pinout and package (QFP2020-112) with all other SH7042 variants including HD6477042F28, HD6477042AF28, and HD6437042AVF16. Pin function definitions, electrical characteristics, and mechanical dimensions are consistent across the SH7042 family per the Hardware Manual's "Pin States" appendix and package diagrams. This enables direct substitution within the same footprint when voltage, frequency, or memory requirements align.
