Product details
Overview
HN58V65AFPI10E from Renesas Electronics is a 64-kbit (8-kword × 8-bit) parallel EEPROM organized with MNOS memory cells and CMOS circuitry, supporting single-supply operation from 2.7 V to 5.5 V, 100 ns access time at 2.7–4.5 V, and 70 ns at 4.5–5.5 V. It features automatic byte/page write (64-byte), Ready/Busy signaling, data polling, and software data protection - used in industrial control modules for nonvolatile parameter storage during power cycling.
For engineers reviewing the HN58V65AFPI10E datasheet, HN58V65AFPI10E pinout, HN58V65AFPI10E application, or HN58V65AFPI10E equivalent, key selection criteria include its 28-pin SOP (FP-28DV) package, −40°C to +85°C operating range (HN58V65AI series), 10⁵ page-program cycles, 10-year data retention, and compatibility with JEDEC byte-wide bus standards.
Technical Context
The HN58V65AFPI10E implements a parallel interface with address latching on CE or WE falling edges and data latching on rising edges. Its internal high-voltage generator enables in-system programming without external VPP, while on-chip address/data latches reduce bus loading and timing constraints.
It supports two write modes: byte-write (≤10 ms max) and page-write (64 bytes in ≤10 ms), with status indication via RDY/Busy pin or I/O7 data polling. The device lacks RES pin functionality - confirmed by pinout documentation showing NC at Pin 3 - distinguishing it from HN58V66A-series variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 64 kbit (8,192 × 8-bit), sufficient for firmware configuration tables or calibration data in microcontroller-based systems |
| Access time | 100 ns max at 2.7–4.5 V; 70 ns max at 4.5–5.5 V - ensures compatibility with 10 MHz bus timing in legacy industrial controllers |
| Write cycle time | 10 ms max per byte or page - enables deterministic timeout handling in real-time applications without polling overhead |
| Data retention | 10 years minimum - guarantees long-term reliability in unattended equipment like remote sensors or metering devices |
| Endurance | 10⁵ erase/write cycles in page mode - supports frequent field-updatable parameters in programmable logic controllers |
| Supply voltage | 2.7 V to 5.5 V single supply - simplifies power design across mixed-voltage systems including 3.3 V and 5 V domains |
| Operating temperature | −40°C to +85°C - qualified for deployment in industrial automation enclosures without active thermal management |
Pinout & Package
HN58V65AFPI10E uses a 400-mil 28-pin plastic SOP package (JEITA code FP-28DV, mass ≈ 0.7 g), lead-free compliant, with standard 1.27 mm pitch and 8.4 mm × 18.3 mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Power supply input (2.7–5.5 V); decoupling capacitor required within 10 mm for noise immunity |
| 2 | WE | Write enable active-low; falling edge latches address, rising edge latches data - critical for synchronous write sequencing |
| 3 | NC | No connection; must be left floating - not RES (confirmed absent in HN58V65A series) |
| 4–13 | A8–A0 | Address inputs (A0–A12 mapped across pins); A0–A12 fully decoded for 8K-word addressing |
| 14 | OE | Output enable active-low; controls tri-state output drivers - enables shared bus operation with other peripherals |
| 15–21 | I/O0–I/O7 | Bidirectional data bus; open-drain compatible with TTL/CMOS logic levels - supports direct MCU GPIO interfacing |
| 22 | RDY/Busy | Open-drain status indicator; low during internal write - eliminates need for fixed delays in host firmware |
| 23–27 | A11–A7 | Additional address bits (A7–A12); A12 is MSB enabling full 8K-word space |
| 28 | VSS | Ground reference; must be connected to system ground plane with low-inductance path |
Key Features
| Feature | Design Value |
|---|---|
| Page write (64 bytes) | Reduces firmware update time by 64× vs. byte writes - critical for efficient field calibration uploads |
| Ready/Busy pin | Hardware flow control eliminates polling loops, freeing CPU cycles in resource-constrained embedded systems |
| Software data protection | Three-byte unlock sequence (0x1555/0x0AAA/0x1555 → 0xAA/0x55/0xA0) prevents accidental writes during noise events |
| Data polling (I/O7 toggle) | Allows status checking using only standard read cycles - no dedicated control pin required for basic implementations |
| JEDEC byte-wide compliance | Ensures drop-in replacement capability with legacy 28-pin EPROM/EEPROM sockets in industrial backplanes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C64B-15PU | 150 ns access time, 5 V only (4.5–5.5 V), no 2.7 V support; 28-pin PDIP only - no SOP variant available | Lacks wide-voltage operation and SOP packaging; requires board redesign for footprint compatibility | Select when legacy 5 V-only systems prioritize Atmel's long-term availability over voltage flexibility |
| MX28F640J3F-12G | 120 ns access, 3.3 V only (3.0–3.6 V); JEDEC-compatible but requires level-shifting for 5 V buses | Not pin-compatible due to different pinout (e.g., no dedicated RDY/Busy); needs PCB layout change | Choose for new 3.3 V designs where higher density (1 Mbit) justifies migration from 64 kbit |
Compared with AT28C64B-15PU and MX28F640J3F-12G, the HN58V65AFPI10E uniquely combines 2.7–5.5 V operation, 28-pin SOP packaging, RDY/Busy signaling, and −40°C to +85°C qualification - making it the only drop-in solution for upgrading legacy 5 V industrial controllers to wider supply and temperature ranges without layout changes.

FAQ
What is the maximum operating temperature range for the HN58V65AFPI10E?
The HN58V65AFPI10E is rated for −40°C to +85°C operation, matching the HN58V65AI series specification. This wide temperature range enables reliable use in industrial enclosures, automotive under-dash locations, and outdoor telecom equipment without thermal derating or additional cooling measures. The device maintains full AC/DC specifications across this entire range when powered within 2.7–5.5 V.
Does the HN58V65AFPI10E support the RES (reset) pin function?
No, the HN58V65AFPI10E does not support the RES pin function. Pin 3 is designated NC (no connection) in the official datasheet, and the RES feature is explicitly reserved for the HN58V66A series only. This distinguishes the HN58V65AFPI10E from its HN58V66AFPI10E counterpart, which includes RES at Pin 3 for hardware write protection during power transitions.
How many write cycles can the HN58V65AFPI10E endure in page mode?
The HN58V65AFPI10E guarantees 10⁵ (100,000) erase/write cycles when operated in page mode, as specified in the datasheet's "Write/Erase Endurance" section. This endurance rating applies to the full 64-byte page and is measured at 1% cumulative failure rate - sufficient for daily field updates over 27+ years in typical industrial applications.
What package type does the HN58V65AFPI10E use, and is it lead-free?
The HN58V65AFPI10E uses a 400-mil 28-pin plastic SOP package (JEITA code FP-28DV) with 1.27 mm pitch and lead-free construction, as indicated by the "-10E" suffix in the part number. Its dimensions are 8.4 mm × 18.3 mm, mass ≈ 0.7 g, and it complies with RoHS Directive 2011/65/EU - suitable for modern automated SMT assembly lines.
Can the HN58V65AFPI10E be used with a 3.3 V microcontroller bus without level shifters?
Yes, the HN58V65AFPI10E supports 3.3 V operation (within its 2.7–5.5 V range) and meets JEDEC byte-wide logic thresholds: VIH ≥ 2.4 V and VIL ≤ 0.6 V at VCC = 3.3 V. Its I/O pins are CMOS-compatible and drive VOH ≥ 0.8×VCC and VOL ≤ 0.4 V, enabling direct connection to 3.3 V MCUs without level translation - verified by DC characteristics tables in Rev. 3.00 datasheet.
