Product details
Overview
HN58X25256FPIAG#S1 from Renesas Electronics is a 256-kbit (32-kword × 8-bit) Serial Peripheral Interface (SPI) EEPROM featuring MONOS memory technology, 1.8 V to 5.5 V single-supply operation, 5 MHz max clock frequency at ≥2.5 V, 32-byte page write capability, and industrial temperature range (−40°C to +85°C). It serves as nonvolatile configuration storage in embedded microcontroller systems requiring reliable parameter retention across power cycles.
For engineers reviewing the HN58X25256FPIAG#S1 datasheet, HN58X25256FPIAG#S1 pinout, HN58X25256FPIAG#S1 application, or HN58X25256FPIAG#S1 equivalent, this device supports SPI Mode 0/3, offers hardware write protection via W and HOLD pins, delivers 1,000k endurance cycles at 25°C, retains data for ≥100 years, and integrates status register control for block-level software protection - critical for firmware update safety and calibration persistence.
Technical Context
This SPI EEPROM implements a serial-parallel converter and address generator with Y/X decoders, enabling byte- and page-level read/write operations over a 4-wire interface (C, D, Q, S). Its internal high-voltage generator supports erase/write without external programming voltage.
The device uses advanced MONOS (Metal-Oxide-Nitride-Oxide-Silicon) charge-trap technology for superior data retention and endurance versus floating-gate EEPROMs, combined with low-voltage CMOS circuitry to achieve standby current ≤2.0 μA and active write current ≤3.5 mA. Status register bits (BP1/BP0/SRWD) enable configurable hardware- and software-based memory protection schemes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 256 kbit (32,768 × 8-bit), supporting full memory read with auto-incremented addressing |
| Supply voltage | 1.8 V to 5.5 V - enables direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Max clock frequency | 5 MHz (at VCC ≥ 2.5 V); 3 MHz (at VCC = 1.8 V) - determines maximum serial throughput for configuration loads |
| Page write size | 32 bytes per page - reduces total write time vs. byte-write by up to 32× for contiguous data |
| Write cycle time | 5 ms typical - defines minimum interval between write commands; impacts firmware update latency |
| Endurance & retention | ≥1,000,000 write/erase cycles at 25°C; ≥100 years data retention at 25°C - ensures long-term field reliability |
| Operating temperature | −40°C to +85°C - qualified for industrial-grade embedded applications including motor control and sensor nodes |
Pinout & Package
HN58X25256FPIAG#S1 is housed in an 8-pin SOP package (PRSP0008DF-B / FP-8DBV), 3.9 mm × 4.89 mm body, 1.27 mm pitch, lead-free and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Accepts 1.8–5.5 V; requires local 0.1 μF bypass capacitor to VSS for noise immunity |
| VSS | Ground reference | Return path for all internal circuits; must be low-impedance connection to system ground |
| S (Chip Select) | Active-low device enable | Drives Q to high-Z when high; falling edge initiates instruction decoding; must be stable during VCC ramp |
| C (Serial Clock) | Interface timing reference | Controls sampling of D (rising edge) and output timing of Q (falling edge); supports SPI Modes 0 and 3 |
| D (Data In) | Serial command/address/data input | Latches instruction opcodes (e.g., 00000010 for WRITE), addresses, and payload on C rising edge |
| Q (Data Out) | Serial data output | Shifts out memory contents or status register bits on C falling edge; high-Z when S is high or HOLD is active |
| W (Write Protect) | Hardware lock control | When low + SRWD=1, disables all status register writes and enforces hardware-protected mode (HPM) |
| HOLD | Communication pause signal | Halts ongoing SPI transfer without deselecting device; Q goes high-Z; C/D become don't-care during hold |
Key Features
| Feature | Design Value |
|---|---|
| MONOS memory cell technology | Enables 1,000k endurance and 100-year data retention without degradation under thermal stress |
| Configurable block protection | BP1/BP0 bits define unprotected regions (none, upper quarter, upper half, or full array) for safe firmware updates |
| Hardware Protected Mode (HPM) | SRWD bit + W pin low locks status register against modification - prevents accidental reconfiguration in field |
| 32-byte page write | Reduces average write time per byte by >95% vs. byte-write, accelerating calibration table storage |
| Low-power active & standby modes | 3.5 mA max write current and 2.0 μA max standby current support battery-backed and energy-constrained designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25SF041-SSHD-B | 4 Mbit density, quad SPI support, 104 MHz max clock, no HOLD pin, different status register layout | Higher bandwidth for firmware caching; lacks HOLD functionality for interrupt-safe pausing | Select when needing faster read throughput or quad I/O; avoid if HOLD-based real-time interrupt handling is required |
| M95M02-DRMN6TP/K | 2 Mbit density, 5 MHz max clock, built-in write protection via WP pin only (no SRWD/BP bits), SO8 package | Simpler protection model; no hardware-locked status register or configurable block protection | Select for cost-sensitive designs where full HPM and BP granularity are unnecessary; verify compatibility with existing SPI driver |
Compared with AT25SF041-SSHD-B and M95M02-DRMN6TP/K, HN58X25256FPIAG#S1 uniquely combines 256 kbit capacity with HOLD pin support, MONOS-based endurance, and dual-layer (software/hardware) write protection - making it optimal for safety-critical embedded systems requiring deterministic, field-robust configuration storage.

FAQ
What is the memory organization of the HN58X25256FPIAG#S1?
HN58X25256FPIAG#S1 provides 256 kbit of storage organized as 32,768 words × 8 bits. It supports full-array sequential reads with automatic address increment and 32-byte page writes. Addressing uses 15-bit addressing (A0–A14), with A15 unused - confirmed in AC Characteristics and Functional Description sections of the datasheet.
Does the HN58X25256FPIAG#S1 support both SPI Mode 0 and Mode 3?
Yes, HN58X25256FPIAG#S1 explicitly supports SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1), as stated in the Features section. This dual-mode compatibility ensures interoperability with diverse host MCUs without requiring clock polarity or phase inversion in firmware.
How does hardware write protection work on the HN58X25256FPIAG#S1?
Hardware write protection on HN58X25256FPIAG#S1 activates when the SRWD bit in the status register is set to 1 and the W pin is driven low - entering Hardware Protected Mode (HPM). In HPM, the SRWD, BP1, and BP0 bits become read-only, and WRSR instructions are rejected, preventing unauthorized status register changes.
What is the maximum write endurance and data retention for the HN58X25256FPIAG#S1?
HN58X25256FPIAG#S1 guarantees ≥1,000,000 write/erase cycles at 25°C and ≥100 years of data retention at 25°C, as specified in the Memory Cell Characteristics table. At 85°C, endurance drops to ≥100,000 cycles and retention to ≥10 years - validated using MONOS memory technology.
Can the HN58X25256FPIAG#S1 operate from a 1.8 V supply?
Yes, HN58X25256FPIAG#S1 operates across 1.8 V to 5.5 V. At 1.8 V, maximum clock frequency is 3 MHz (per AC Characteristics, Ta = −40 to +85°C), and DC operating conditions confirm VIH/VIL thresholds scale correctly. All functional features - including HOLD, W protection, and status register access - remain fully operational at 1.8 V.
