Product details
Overview
HN58V65ATI10E from Renesas Electronics is a 64-kbit (8-kword × 8-bit) parallel EEPROM organized with MNOS memory cells and CMOS circuitry, supporting 2.7–5.5 V single-supply operation, 100 ns access time at 2.7–4.5 V, and 70 ns at 4.5–5.5 V. It delivers 10⁵ erase/write cycles in page mode, 10-year data retention, and operates across −40°C to +85°C - used for firmware storage and configuration data backup in industrial control modules.
For engineers reviewing the HN58V65ATI10E datasheet, HN58V65ATI10E pinout, HN58V65ATI10E application, or HN58V65ATI10E equivalent, key selection criteria include its TSOP-28 package, RDY/Busy signaling, software data protection sequence (AA/55/A0), 64-byte page write capability, and compatibility with JEDEC byte-wide standard interfaces.
Technical Context
The HN58V65ATI10E implements a parallel byte-wide interface with address latching on CE or WE falling edges and data latching on rising edges. Its internal architecture includes on-chip address/data latches, high-voltage generator for programming, and dual-mode write control (CE- or WE-controlled).
It supports three status-monitoring methods: RDY/Busy pin output (active-low during write), data polling via I/O7 inversion, and toggle-bit detection on I/O6 - enabling flexible host synchronization without fixed timing delays. Software data protection requires a 3-byte unlock sequence before write operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 64 kbit (8,192 × 8-bit), sufficient for boot code or calibration tables in microcontroller-based systems |
| Access time | 100 ns max at 2.7–4.5 V; 70 ns max at 4.5–5.5 V - enables direct interfacing with 10 MHz bus systems |
| Write cycle time | 10 ms max per byte or 64-byte page - deterministic timing for host firmware timeout handling |
| Data retention | 10 years minimum after ≤10⁴ page-program cycles - meets long-life industrial equipment requirements |
| Endurance | 10⁵ erase/write cycles in page mode - supports frequent field-upgrade scenarios |
| Supply voltage | 2.7–5.5 V single supply - interoperable with 3.3 V and 5 V logic families without level translation |
| Operating temperature | −40°C to +85°C - qualified for industrial-grade embedded applications |
Pinout & Package
HN58V65ATI10E uses a 28-pin plastic TSOP (TFP-28DBV) package, 8.0 mm × 13.4 mm footprint, 1.2 mm max height, lead-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address input | 13-bit address bus for full 8-kword addressing; A6–A12 serve as page address latch points |
| I/O0–I/O7 | Data input/output | Bi-directional 8-bit data bus; I/O7 used for data polling, I/O6 for toggle-bit status monitoring |
| CE | Chip enable | Active-low chip select; falling edge latches address, rising edge latches data in CE-controlled write mode |
| OE | Output enable | Active-low read control; enables data output only when CE is also low |
| WE | Write enable | Active-low write control; falling edge latches address, rising edge latches data in WE-controlled write mode |
| RDY/Busy | Ready/Busy indicator | Open-drain output pulled low during internal write; high-impedance otherwise - allows wired-OR status sharing |
| VCC / VSS | Power / Ground | Single 2.7–5.5 V supply; decoupling required within 10 mm of pins per JEDEC guidelines |
| NC | No connection | Pin 3 is unconnected; must be left floating or tied to VSS per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| 64-byte page write | Reduces firmware update time by up to 64× vs. byte writes - critical for field OTA updates |
| RDY/Busy + data polling + toggle bit | Three independent status reporting methods allow host MCU to choose optimal synchronization strategy |
| Software data protection | 3-byte unlock sequence (1555h/AAh → 0AAAh/55h → 1555h/A0h) prevents accidental writes during power transients |
| Data protection on power on/off | Hardware circuitry inhibits write initiation during VCC ramp-up/down - eliminates need for external reset supervision |
| JEDEC byte-wide standard compliance | Ensures drop-in compatibility with legacy 28-pin parallel EEPROM designs and socketed test fixtures |

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 RDY/Busy pin; 10⁴ endurance | Lacks status signaling and wide-VCC support - requires polling-only host logic and external voltage regulation | Choose for cost-sensitive 5 V-only legacy designs where timing margin exists and status feedback is unnecessary |
| BR24T64FJ-WE2 | I²C interface; 1 MHz clock; 1.7–5.5 V; 10⁶ endurance; no page write | Serial interface reduces pin count but increases write latency; incompatible with parallel bus architectures | Prefer for space-constrained designs with existing I²C infrastructure and lower write-frequency requirements |
Compared with AT28C64B-15PU and BR24T64FJ-WE2, the HN58V65ATI10E uniquely combines parallel-speed access, multi-voltage operation, integrated status signaling, and page-write acceleration - making it optimal for real-time industrial hosts needing deterministic, high-cycle-count nonvolatile storage.

FAQ
What is the maximum write speed supported by the HN58V65ATI10E?
The HN58V65ATI10E supports 64-byte page writes completing in ≤10 ms, achieving an effective throughput of 6.4 kB/s. Byte writes also complete within 10 ms. This performance is guaranteed across the full 2.7–5.5 V supply range and −40°C to +85°C temperature span, with no derating required. The HN58V65ATI10E achieves this using on-chip address/data latches and optimized MNOS cell programming.
Does the HN58V65ATI10E support both CE-controlled and WE-controlled write modes?
Yes, the HN58V65ATI10E supports two distinct write control protocols: CE-controlled (where CE falling edge latches address and CE rising edge latches data) and WE-controlled (where WE falling edge latches address and WE rising edge latches data). Both modes are fully documented in the AC characteristics tables and timing waveforms of the HN58V65ATI10E datasheet, enabling flexible integration with diverse microcontroller bus timing constraints.
How does software data protection work on the HN58V65ATI10E?
Software data protection on the HN58V65ATI10E requires a precise 3-byte unlock sequence: write 0xAA to address 0x5555, then 0x55 to address 0x2AAA, then 0xA0 to address 0x5555. Only after this sequence can subsequent writes succeed. The HN58V65ATI10E exits protection mode automatically after power-on reset, and the feature is disabled at shipment. No hardware RES pin is present on the HN58V65ATI10E variant.
Is the HN58V65ATI10E pin-compatible with older 28-pin parallel EEPROMs?
Yes, the HN58V65ATI10E uses the JEDEC-standard 28-pin TSOP (TFP-28DBV) footprint and matches the pinout of industry-standard 64-kbit parallel EEPROMs including the AT28C64B and X28C64. Address (A0–A12), data (I/O0–I/O7), and control (CE/OE/WE/RDY/Busy/VCC/VSS) signals occupy identical positions, enabling direct PCB-level replacement without layout modification.
What are the key reliability specifications of the HN58V65ATI10E?
The HN58V65ATI10E guarantees 10⁵ erase/write cycles in page mode and 10 years of data retention when programmed ≤10⁴ times. It meets JEDEC standards for input leakage (<2 µA), output leakage (<2 µA), and withstands absolute maximum ratings including −0.6 V to +7.0 V on VCC and −0.5 V to +7.0 V on inputs. These specs are validated across −40°C to +85°C operation, confirming suitability for mission-critical industrial deployments.
