Product details
Overview
HN58X25128FPI#S0 from Renesas Electronics is a 128-kbit (16-kword × 8-bit) SPI-compatible serial EEPROM featuring MONOS memory technology, 1.8 V to 5.5 V single-supply operation, 32-byte page programming, and industrial temperature range (−40°C to +85°C). It delivers high reliability with 1,000k write cycles and 100-year data retention at 25°C, used for firmware parameter storage in embedded controllers.
For engineers reviewing the HN58X25128FPI#S0 datasheet, HN58X25128FPI#S0 pinout, HN58X25128FPI#S0 application, or HN58X25128FPI#S0 equivalent, key selection considerations include its 3 MHz max clock frequency at 1.8 V, hardware/software write protection via W and SRWD/BP bits, HOLD functionality for bus arbitration, and SOP-8 package compatibility with legacy board layouts.
Technical Context
This device implements a standard SPI interface (modes 0 and 3), supporting full-duplex serial communication with chip-select–driven activation and HOLD–enabled pause capability. Its internal architecture includes a 32-byte page buffer, status register with WIP/WEL/BP1/BP0/SRWD bits, and voltage detector for power-on reset.
Write operations are self-timed (5 ms typical), require prior WREN instruction, and support both byte and page writes within the same 32-byte boundary. Protection logic enforces dual-layer security: software block protection (BP1/BP0) and hardware-locked status register (SRWD + W pin state).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128 kbit (16,384 × 8-bit), enabling storage of configuration tables or calibration data for mid-complexity microcontrollers |
| Supply voltage | 1.8 V to 5.5 V - supports direct interfacing with 1.8 V, 3.3 V, and 5 V logic domains without level shifters |
| Max clock frequency | 3 MHz at 1.8 V / 5 MHz at 2.5–5.5 V - determines maximum sequential read/write throughput in host system |
| Page size | 32 bytes - defines minimum efficient write granularity; crossing page boundary wraps address and overwrites prior data |
| Endurance & retention | 1,000k cycles @25°C / 100 years @25°C - qualifies for long-life industrial control and metering applications |
| Operating temperature | −40°C to +85°C - meets extended industrial ambient requirements without derating |
| Write protect | Hardware-enabled via W pin + SRWD bit - prevents accidental writes during power transitions or noise events |
Pinout & Package
HN58X25128FPI#S0 is housed in an 8-pin SOP package (PRSP0008DF-B, 3.9 mm × 4.89 mm, 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 ceramic bypass capacitor to VSS for noise immunity |
| VSS | Ground reference | System ground return path; must be low-impedance and co-located with bypass capacitor |
| S (Chip Select) | Device enable control | Active-low signal; falling edge initiates instruction decode; rising edge terminates read/write cycles |
| C (Serial Clock) | Interface timing reference | Drives synchronous data transfer; supports modes 0 (CPOL=0, CPHA=0) and 3 (CPOL=1, CPHA=1) |
| D (Data In) | Serial command/address/data input | Latches instruction opcodes, addresses, and write data on rising clock edge |
| Q (Data Out) | Serial data output | Drives read data on falling clock edge; enters 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 permanent block protection |
| HOLD | Bus hold control | Pauses ongoing SPI transaction without deselecting device; requires C to be low for valid assertion |
Key Features
| Feature | Design Value |
|---|---|
| MONOS memory technology | Enables ultra-high endurance (1M cycles) and 100-year data retention without charge-pump wear-out mechanisms |
| 32-byte page programming | Reduces average write time per byte by up to 32× versus byte-write mode, accelerating firmware update routines |
| Dual protection architecture | Combines software-configurable BP1/BP0 block locks with hardware-enforced SRWD+W locking for tamper-resistant storage |
| HOLD function | Allows host MCU to suspend EEPROM communication mid-transfer for higher-priority tasks without losing state or requiring reinitialization |
| Power-on reset (POR) | Prevents spurious writes during VCC ramp-up/down by ignoring S transitions until stable supply is detected |
Applications
| Industrial PLC Configuration Storage | Smart Meter Calibration Data Retention |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25128B-SSHL-T (Microchip) | Same 128 kbit density, 32-byte page, and SPI modes; lower max clock (20 MHz vs 5 MHz) but tighter tV (60 ns vs 70 ns) | Higher-speed read bursts possible; lacks HOLD pin - requires software-managed bus arbitration | Select if system demands faster random reads and can implement HOLD-equivalent logic in firmware |
| M95128-DRMN3TP/K (STMicroelectronics) | Identical 128 kbit/32-byte/page spec; adds deep power-down mode (1 μA) not present in HN58X25128FPI#S0 | Better suited for battery-powered nodes needing ultra-low standby current between wake-ups | Choose when energy budget is constrained and deep-sleep duty cycle exceeds 99% of operational time |
Compared with AT25128B-SSHL-T and M95128-DRMN3TP/K, HN58X25128FPI#S0 provides native HOLD functionality and MONOS-based endurance/reliability advantages, making it optimal for industrial systems requiring robust bus sharing and long-term field stability without firmware overhead.

FAQ
What is the maximum clock frequency supported by HN58X25128FPI#S0 at 1.8 V?
HN58X25128FPI#S0 supports a maximum clock frequency of 3 MHz when operated at 1.8 V. This is specified in the AC Characteristics table for VCC = 1.8 V to 5.5 V. At higher supply voltages (2.5 V to 5.5 V), the device supports up to 5 MHz. The 3 MHz limit at 1.8 V ensures timing margin compliance under low-voltage conditions.
Does HN58X25128FPI#S0 support hardware write protection independent of software configuration?
Yes, HN58X25128FPI#S0 supports hardware write protection via the combination of the W pin and SRWD bit. When SRWD = 1 and W is driven low, the status register becomes permanently read-only, disabling all WRSR instructions and freezing BP1/BP0 protection settings - even if WEL is set. This hardware lock persists across power cycles.
How many bytes can be written in a single page program cycle for HN58X25128FPI#S0?
HN58X25128FPI#S0 supports 32-byte page programming. A single WRITE instruction can load up to 32 consecutive bytes starting from any address aligned to a 32-byte boundary. If more than 32 bytes are sent, the address counter wraps within the page, overwriting earlier data in that same 32-byte segment.
What is the purpose of the HOLD pin on HN58X25128FPI#S0, and what timing condition must be met to activate it?
The HOLD pin on HN58X25128FPI#S0 pauses ongoing SPI communication without deselecting the device or resetting internal state. To activate HOLD, the signal must be driven low while the serial clock (C) is simultaneously low. Deactivation requires HOLD to go high while C remains low. This ensures deterministic bus arbitration in multi-master systems.
Is HN58X25128FPI#S0 compatible with SPI Mode 0 and Mode 3, and how is this selected?
Yes, HN58X25128FPI#S0 is compatible with both SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1). No configuration is required - the device automatically detects and adapts to either mode based on the clock polarity and phase timing of the host controller's SCK signal.
