Product details
Overview
HD6477043AFI28V from Renesas Electronics is a 32-bit RISC microcontroller in the SH7043A family, featuring a SH-2 CPU core, 128 kB on-chip mask ROM, 32-bit external bus interface, and integrated peripherals including A/D converter, timers, SCI, and DMA controller. It operates at up to 28 MHz with 5 V supply and targets industrial embedded control applications requiring deterministic real-time response.
For engineers reviewing the HD6477043AFI28V datasheet, HD6477043AFI28V pinout, HD6477043AFI28V application, or HD6477043AFI28V equivalent, this page delivers verified technical context, package mapping, functional specifications, and validated alternative options for system design and component selection.
Technical Context
The HD6477043AFI28V implements the SH-2 RISC architecture with single-cycle instruction execution for high throughput, supported by a 32-bit internal bus and 1-kbyte on-chip cache to accelerate external memory access. Its peripheral set includes a 8-channel 10-bit A/D converter with ±4 LSB accuracy, four multifunction timer units (MTU), two serial communication interfaces (SCI), and a 4-channel DMA controller with independent transfer count and channel control registers.
It supports multiple operating modes-user, standby, and power-down-with configurable pin states during reset and bus release. The device uses a QFP2020-144 package with copper lead material, rated for –20°C to +75°C operation, and integrates Schmitt-trigger inputs on selected I/O pins (PA2, PA5–PA9, PE0–PE15) for noise immunity in industrial environments.

Pinout & Package
HD6477043AFI28V is housed in a 144-pin QFP (QFP2020-144) package with 0.5 mm pitch and copper lead material. Pin functions are defined across six I/O ports (PA–PF), address/data multiplexed bus lines (A0–A21, D0–D31), control signals (RD/WR, CS0–CS3, RAS/CAS), and dedicated peripheral pins (TIOCx, SCKx, RXD/TXD, AN0–AN7).

|---|---|---|
| PA0–PA23 | General-purpose I/O port A | Configurable as input/output; some pins support alternate functions (AH, CK, IRQ) |
| D0–D31 | 32-bit bidirectional data bus | Used for memory and peripheral transfers; high-impedance during bus release |
| A0–A21 | 22-bit address bus (multiplexed) | Provides upper address bits for external memory mapping; A21–A18 are input-only after reset |
| CS0–CS3 | Chip select outputs | Enable external devices in four independent memory or I/O spaces |
| AN0–AN7 | Analog input channels | Accept 0–Vref voltage range; require external protection circuit per Figure 15.14 |

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 |
|---|---|---|---|
| HD6477043AVF16 | Same SH-2 core and 128 kB mask ROM, but rated for 16 MHz max clock and 3.3 V supply | Lower power consumption; unsuitable for 28 MHz timing-critical control loops | Select when system clock budget is ≤16 MHz and 3.3 V rail is available |
| HD64F7045F28 | 256 kB on-chip flash memory instead of mask ROM; same 28 MHz/5 V rating and QFP2020-144 package | Enables field firmware updates; requires flash programming infrastructure and longer boot time | Select when firmware flexibility and post-deployment updates are required over cost-optimized mask ROM |

FAQ
What is the maximum operating frequency of the HD6477043AFI28V?
The HD6477043AFI28V is rated for a maximum CPU clock frequency of 28 MHz under 5 V supply conditions. It also supports 16 MHz operation for reduced power consumption. Electrical characteristics, including timing parameters and A/D accuracy, are guaranteed only at these specified frequencies - exceeding 28 MHz violates the device's operational limits and may cause functional failure.
Does the HD6477043AFI28V include on-chip RAM?
No, the HD6477043AFI28V does not integrate on-chip RAM. It features 128 kB of mask-programmed ROM for program storage but relies entirely on external memory (SRAM, DRAM, or Flash) for data and stack operations. The external bus interface supports 32-bit data width and configurable wait states to accommodate various memory technologies.
What A/D converter accuracy is specified for the HD6477043AFI28V?
The HD6477043AFI28V specifies ±4 LSB integral nonlinearity for its 10-bit A/D converter when operated at 16.7 MHz conversion clock. This accuracy applies to all eight analog input channels (AN0–AN7) and is measured under 5 V supply conditions. External analog front-end filtering and proper PCB layout per Figure 15.14 are required to achieve this specification.
Is the HD6477043AFI28V pin-compatible with other SH7043A variants?
Yes, HD6477043AFI28V shares the same QFP2020-144 package and pinout with other SH7043A variants including HD6477043AVF16, HD6477043ACF28, and HD6477043AVCF16. All share identical pin assignments, electrical drive characteristics, and reset behavior - enabling hardware reuse across speed and voltage grades within the SH7043A family.
What industrial temperature range does the HD6477043AFI28V support?
The HD6477043AFI28V is qualified for industrial operation from –20°C to +75°C ambient temperature. This range is explicitly stated in the SH7040 Series Hardware Manual and applies to all electrical and timing specifications. Operation outside this range is not guaranteed and may result in parametric drift or functional failure.
