Product details
Overview
HD6477034X20V from Renesas Technology Corp. is a 32-bit RISC microcontroller based on the SuperH™ SH1-DSP CPU core, featuring on-chip PROM, 5.0 V operation, 20 MHz max clock frequency, -20 to +75°C temperature range, and 120-pin TQFP (PTQP0120LA-A) package - used as main system controller in industrial HMI and embedded instrumentation.
For engineers reviewing the HD6477034X20V datasheet, HD6477034X20V pinout, HD6477034X20V application, or HD6477034X20V equivalent, key selection criteria include on-chip PROM capacity, 5 V I/O compatibility, integrated DMAC/ITU/SCI peripherals, and support for MCU Mode 0 with external memory expansion via BSC.
Technical Context
The HD6477034X20V implements the SH-1 instruction set with 32-bit internal architecture, supporting PC-relative addressing, MAC.W for 16×16→42-bit signed multiply-accumulate, and dual-mode interrupt handling via INTC with priority registers IPRA–IPRE. It executes instructions in single-cycle pipeline stages with optional wait-state insertion controlled by WCR1–WCR3.
Its peripheral integration includes a Bus State Controller (BSC) for DRAM interface and refresh control, Direct Memory Access Controller (DMAC) with auto-request and cycle-steal modes, and a 16-bit Integrated Timer Pulse Unit (ITU) supporting PWM, input capture, and reset-synchronized waveform generation - all mapped to fixed addresses in the on-chip peripheral module space (H'5FFFE00–H'5FFFFFF).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD6477034F20 | Same SH1-DSP core and peripherals, but in 112-pin QFP (PRQP0112JA-A); lacks A16–A19 and D16–D15 pins | Lower pin count limits external memory expansion and I/O concurrency; suitable for space-constrained designs with reduced peripheral needs | Select HD6477034F20 only when board layout requires smaller footprint and full 120-pin functionality is unnecessary |
| HD6477034VF12 | 3.3 V supply version with 12.5 MHz max frequency; uses same 112-pin QFP package as F20 variant | Lower voltage and frequency reduce power consumption but eliminate compatibility with 5 V buses and high-speed timing-critical tasks | Choose HD6477034VF12 only for low-power portable instruments where 5 V interface support is not required |
Compared with HD6477034F20 and HD6477034VF12, the HD6477034X20V uniquely combines 120-pin expandability, 5 V operation, and 20 MHz performance - making it the sole option among SH7034 variants for systems requiring full external memory interface bandwidth and legacy voltage compatibility.

FAQ
What is the maximum operating frequency of the HD6477034X20V?
The HD6477034X20V operates at a maximum frequency of 20 MHz when supplied with 5.0 V. This rating is specified under DC characteristics and confirmed in the Hardware Manual Rev. 7.00, Table 1.2 Product Lineup. Operation above this frequency may result in undefined behavior or timing violations in the SH1-DSP core or peripheral modules such as ITU or DMAC. The HD6477034X20V does not support frequency scaling or PLL-based clock multiplication.
Does the HD6477034X20V include on-chip RAM?
No, the HD6477034X20V does not integrate on-chip RAM. According to the SH7032/SH7034 Hardware Manual Rev. 7.00, Section 18 "RAM", on-chip RAM is present only in SH7032 variants (e.g., HD6417032). The HD6477034X20V relies entirely on external memory accessed via its 16-bit data bus and BSC-controlled address space. System designers must provide external SRAM or DRAM for stack, variables, and buffers.
What package type is used for the HD6477034X20V?
The HD6477034X20V uses a 120-pin plastic thin quad flat pack (TQFP), identified by Renesas package code PTQP0120LA-A. This differs from the 112-pin QFP (PRQP0112JA-A) used for HD6477034F20/FI20 variants. The extra pins support expanded address/data bus width (A16–A19, D16–D15) and additional I/O for complex peripheral interfacing, as documented in Section 1.3.1 "Pin Arrangement" of the Hardware Manual.
Is the HD6477034X20V pin-compatible with other SH7034 variants?
No, the HD6477034X20V is not pin-compatible with other SH7034 variants. Its 120-pin TQFP (PTQP0120LA-A) package has different pin count, pitch, and signal assignment than the 112-pin QFP packages used for HD6477034F20 and HD6477034VF12. Pin mappings for /CS, /WAIT, and peripheral control signals also differ due to expanded bus width. PCB layout must be redesigned to accommodate the HD6477034X20V.
What development tools are supported for the HD6477034X20V?
The HD6477034X20V is supported by Renesas' legacy SH-1 toolchain, including the C/C++ Compiler (REJ10B0152-0101), Simulator Debugger (REJ10B0210-0200), and High-performance Embedded Workshop (REJ10J0886-0300). These tools target the SH1-DSP instruction set and require configuration for 5 V operation and MCU Mode 0 startup. No modern IDE or cloud-based toolchain officially supports HD6477034X20V due to its end-of-life status.
