Product details
Overview
HN58V65AT10SRE 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 Ready/Busy status signaling. It delivers high reliability for nonvolatile data storage in industrial control modules requiring frequent firmware parameter updates.
For engineers reviewing the HN58V65AT10SRE datasheet, HN58V65AT10SRE pinout, HN58V65AT10SRE application, or HN58V65AT10SRE equivalent, key selection criteria include its −20°C to +85°C operating range, 64-byte page write capability, software data protection sequence, RDY/Busy output timing, and TSOP-28 package compatibility with legacy 28-pin parallel memory footprints.
Technical Context
This device implements byte- and page-write operations using edge-triggered address latching on WE or CE falling edges, with automatic internal write completion within 10 ms. Data polling via I/O7 and toggle-bit detection on I/O6 provide real-time write-status feedback without external timing dependencies.
The HN58V65AT10SRE belongs to the HN58V65A-SR series and lacks the RES reset pin found in HN58V66A variants-its data protection relies solely on software command sequences and noise immunity on control pins (CE/OE/WE), with hardware write inhibit achieved by holding CE high or OE low during power transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 64 kbit (8,192 × 8-bit), sufficient for storing configuration tables or calibration data in microcontroller-based systems |
| Supply voltage | 2.7 V to 5.5 V - supports direct interface with 3.3 V and 5 V logic families without level shifting |
| Access time | 100 ns max at 2.7–4.5 V; 70 ns max at 4.5–5.5 V - enables integration into fast 8-bit bus architectures |
| Write cycle time | 10 ms max per byte or 64-byte page - deterministic timing simplifies firmware wait-state implementation |
| Data retention | 10 years minimum after ≤10⁴ page-program cycles - ensures long-term validity of stored parameters in unattended equipment |
| Endurance | 10⁵ erase/write cycles in page mode - suitable for applications requiring daily reconfiguration over 27 years |
| Operating temperature | −20°C to +85°C - qualified for commercial and extended-industrial environments, excluding automotive-grade extremes |
Pinout & Package
HN58V65AT10SRE uses a 28-pin plastic TSOP (TFP-28DB) package, 8.0 mm × 13.4 mm footprint, 1.2 mm max height, lead-free compliant. Pinout matches JEDEC-standard parallel EEPROM layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A12 | Address input | 13-bit address bus supporting full 8-kword addressing; A6–A12 serve as page address bits latched on first WE/CE edge |
| I/O0–I/O7 | Data input/output | Bidirectional 8-bit data bus; I/O7 used for data polling, I/O6 for toggle-bit status indication during writes |
| CE | Chip enable | Active-low chip select; must be held low for read/write; high state places device in standby (110 µW max) |
| OE | Output enable | Active-low output control; disables data bus drivers when high, enabling bus sharing |
| WE | Write enable | Active-low write strobe; falling edge latches address and initiates byte/page programming sequence |
| RDY/Busy | Status output | Open-drain signal pulled low during internal write; high-impedance otherwise - allows wired-OR monitoring |
| VCC | Power supply | 2.7–5.5 V main supply; decoupling capacitor required near pin for noise immunity during write transitions |
| VSS | Ground | Reference return path; requires low-impedance connection to system ground plane |
| NC | No connection | Pin 3 is unconnected; must remain floating - no external tie required |
Key Features
| Feature | Design Value |
|---|---|
| 64-byte page write | Reduces firmware overhead by enabling burst writes up to 64 bytes with single command initiation and 10 ms total latency |
| Software data protection | Prevents accidental writes via 3-byte unlock sequence (AAh→55h→A0h at specific addresses), eliminating need for external hardware write protect |
| RDY/Busy and data polling | Provides two independent, pin-compatible methods to detect write completion - simplifies host driver development across diverse MCU platforms |
| Noise immunity on control lines | Rejects transients ≤15 ns on CE/OE/WE, preventing spurious writes during EMI events or power-up sequencing |
| On-chip address/data latches | Eliminates need for external bus latches in microprocessor systems, reducing BOM count and PCB area |

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 | 5 V only (4.5–5.5 V); 150 ns access; no RDY/Busy pin; 100 k-cycle endurance | Lacks hardware status signaling; requires polling-only firmware design; narrower voltage range limits mixed-voltage system use | Choose when cost sensitivity outweighs timing and status-feature requirements in 5 V-only designs |
| FM24CL64-G | I²C interface; 400 kHz clock; 3.3 V operation; no page write; 10¹⁴ endurance | Serial interface reduces pin count but increases write latency; no parallel bus compatibility; ultra-high endurance suits logging applications | Prefer for space-constrained designs where serial interface and extreme endurance justify slower write throughput |
Compared with AT28C64B-15PU and FM24CL64-G, the HN58V65AT10SRE uniquely balances parallel-speed access, hardware-ready signaling, wide-voltage operation, and page-write efficiency-making it optimal for legacy 8-bit bus upgrades where deterministic timing and minimal firmware changes are critical.

FAQ
What is the operating temperature range for the HN58V65AT10SRE?
The HN58V65AT10SRE is rated for operation from −20°C to +85°C. This defines its qualification as an extended-commercial grade device, suitable for indoor industrial equipment and consumer electronics but not for automotive under-hood or military applications requiring wider ranges. The HN58V65AT10SRE datasheet specifies this range explicitly in the Recommended DC Operating Conditions table on page 6.
Does the HN58V65AT10SRE support hardware write protection via a RES pin?
No, the HN58V65AT10SRE does not include a RES (reset) pin. That feature is exclusive to the HN58V66A-series variants, as confirmed in the Pin Description table (page 4) and Functional Description section (page 19). The HN58V65AT10SRE relies entirely on software data protection (3-byte unlock sequence) and proper control-pin biasing during power transitions for write inhibition.
How does the RDY/Busy signal function on the HN58V65AT10SRE?
The RDY/Busy pin on the HN58V65AT10SRE is an open-drain output that pulls low during internal write operations and returns to high-impedance afterward. It is electrically compatible with standard TTL/CMOS logic and can be wire-OR'd with other status signals. The HN58V65AT10SRE datasheet confirms its behavior in the Operation Table (page 5) and Functional Description (page 19).
What package type is used by the HN58V65AT10SRE?
The HN58V65AT10SRE uses a 28-pin plastic TSOP (Thin Small Outline Package) designated TFP-28DB, measuring 8.0 mm × 13.4 mm with a maximum height of 1.2 mm. Package dimensions are documented on page 26 of the datasheet, and the "SRE" suffix in the part number explicitly denotes the lead-free TSOP variant.
Can the HN58V65AT10SRE perform page writes, and what is the maximum page size?
Yes, the HN58V65AT10SRE supports automatic page writes of up to 64 bytes per command, as stated in the Features section (page 1) and detailed in the Functional Description (page 19). Each page write completes internally within 10 ms, and successive bytes must be loaded within 30 µs of the prior WE or CE falling edge to remain in page mode.
