Product details

Overview

HN58X25128BTI#S0 from Renesas Electronics is a 128-kbit (16-kword × 8-bit) SPI-compatible 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 −40°C to +85°C temperature range - deployed for firmware parameter storage in embedded control modules.

For engineers reviewing the HN58X25128BTI#S0 datasheet, HN58X25128BTI#S0 pinout, HN58X25128BTI#S0 application, or HN58X25128BTI#S0 equivalent, key selection criteria include verified 128-kbit density, SOP-8 package compatibility, hardware/software write protection support via W and SRWD/BP bits, and guaranteed 1,000k endurance cycles at 25°C.

Technical Context

This device implements a Serial Peripheral Interface (SPI) with Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) support, enabling interoperability with diverse microcontrollers. Its internal architecture integrates a high-voltage generator, Y/X decoders, sense amplifiers, and serial-parallel conversion logic to manage 16,384 × 8-bit memory array access.

Write operations use automatic 32-byte page programming with self-timed 5 ms write cycle time; read operations deliver data on Q at up to 5 MHz with output valid within 70 ns after clock low. Protection logic combines volatile WEL bit control, non-volatile BP1/BP0 block protection, and SRWD-enabled Hardware Protected Mode (HPM) when W is low.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory size	128 kbit (16,384 × 8-bit), sufficient for storing bootloader configuration, calibration tables, or device identity data in space-constrained designs.
Supply voltage	1.8 V to 5.5 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifting.
Max clock frequency	5 MHz (at VCC ≥ 2.5 V); 3 MHz (at VCC = 1.8 V to 5.5 V) - enables fast parameter updates while maintaining timing compliance across voltage ranges.
Page write size	32 bytes per page - reduces total write time versus byte-wise writes; critical for logging burst data or updating multi-byte registers atomically.
Endurance & retention	1,000k write/erase cycles at 25°C; 100-year data retention at 25°C - ensures long-term reliability in infrequently updated but mission-critical storage applications.
Operating temperature	−40°C to +85°C - qualified for industrial automation, automotive body electronics, and outdoor IoT edge nodes.
Package	SOP-8 (PRSP0008DF-B / FP-8DBV), 3.9 mm × 4.89 mm footprint - compatible with standard reflow processes and legacy PCB layouts.

Pinout & Package

SOP-8 plastic package (PRSP0008DF-B, JEITA code FP-8DBV), 150-mil width, lead-free and halogen-free (#S0 suffix).

Pin/Terminal	Circuit Role	Design Meaning
1 S	Chip select	Active-low enable signal; must transition low before any instruction; high-Z output when high; initiates standby mode when deasserted.
2 W	Write protect	Hardware-level control for Status Register Write Disable (SRWD) mode; low enables Hardware Protected Mode (HPM), freezing BP1/BP0 and SRWD bits.
3 C	Serial clock	Provides timing for SPI interface; instructions and addresses latched on rising edge; Q data changes on falling edge; supports Mode 0/3.
4 D	Serial data input	Receives instruction opcodes (e.g., 00000010 for WRITE), 16-bit addresses, and data bytes; sampled on rising edge of C.
5 Q	Serial data output	Transmits status register contents or memory array data; driven low-impedance during active READ; high-Z when S or HOLD is high.
6 HOLD	Hold control	Pauses ongoing SPI transaction without deselecting device; requires S low and C low to activate; Q goes high-Z, D/C ignored.
7 VSS	Ground	Reference return path for all I/O and core logic; requires local 0.1 μF ceramic bypass capacitor to VCC per datasheet layout guidance.
8 VCC	Supply voltage	1.8–5.5 V power input; includes internal power-on reset to prevent spurious writes during power ramp; turn-on rate ≤2 μs/V required.

Key Features

Feature	Design Value
MONOS memory technology	Enables high reliability and extended data retention (100 years @25°C) with low-voltage operation and reduced charge loss vs. floating-gate EEPROM.
Hardware + software write protection	Combines W pin-driven Hardware Protected Mode (HPM) with SRWD/BP1/BP0 bits for layered security - prevents accidental or malicious firmware corruption.
32-byte page programming	Reduces typical write latency by up to 32× versus byte-write; supports atomic updates of multi-byte parameters like PID coefficients or sensor offsets.
Low-power active/standby states	3.5 mA max active write current and 2.0 μA max standby current enable battery-backed or energy-harvesting system integration.
SPI Mode 0/3 compatibility	Ensures plug-and-play interoperability with ARM Cortex-M, Renesas RA/RX, Microchip PIC, and ST STM32 MCUs without custom driver adaptation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar SPI EEPROM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AT25128B-SSHL-T (Microchip)	128-kbit SPI EEPROM, 2.5–5.5 V supply, 20 MHz max clock, 64-byte page size, SOIC-8 package.	Higher speed and larger page size suit high-throughput logging; lacks HOLD pin and MONOS reliability advantages.	Select when system requires faster write throughput and supports 20 MHz SPI; verify HOLD functionality is not needed in host firmware.
M95128-DRMN6TP/K (STMicroelectronics)	128-kbit SPI EEPROM, 1.8–5.5 V supply, 5 MHz max clock, 32-byte page size, TSSOP-8 package, built-in write protection.	Same voltage range and page size; TSSOP-8 offers smaller footprint but lower thermal mass than SOP-8; no dedicated HOLD pin.	Choose for space-constrained designs where TSSOP-8 is preferred; confirm board layout accommodates different thermal profile during reflow.

Compared with HN58X25128BTI#S0, AT25128B-SSHL-T offers higher bandwidth but sacrifices HOLD functionality and MONOS-based longevity, while M95128-DRMN6TP/K matches voltage and page size in a denser TSSOP package but omits HOLD - making HN58X25128BTI#S0 optimal for robust, feature-complete industrial SPI EEPROM needs.

FAQ

What is the memory organization of the HN58X25128BTI#S0?

HN58X25128BTI#S0 provides 128 kbit of storage organized as 16,384 words × 8 bits. This structure supports byte-aligned reads and writes, with address range A0–A13 (14-bit addressing). The device uses 32-byte pages for efficient programming, and all memory locations are accessible via standard SPI READ and WRITE instructions as defined in the Renesas datasheet.

Does the HN58X25128BTI#S0 support both SPI Mode 0 and Mode 3?

Yes, the HN58X25128BTI#S0 is explicitly compatible with SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1), as confirmed in the official Renesas datasheet. This dual-mode support ensures interoperability with a wide range of microcontrollers including Renesas RX/RA families, STMicroelectronics STM32, and NXP Kinetis devices without requiring hardware modifications or custom timing adjustments.

How does hardware write protection work on the HN58X25128BTI#S0?

Hardware write protection on the HN58X25128BTI#S0 is activated when the W pin is driven low *and* the SRWD bit in the status register is set to 1 - entering Hardware Protected Mode (HPM). In HPM, the non-volatile BP1, BP0, and SRWD bits become read-only, and WRSR instructions are rejected. This prevents unauthorized modification of protection settings even if the WEL bit is set, providing tamper-resistant configuration locking.

What is the maximum write cycle time for the HN58X25128BTI#S0?

The maximum write cycle time for the HN58X25128BTI#S0 is 5 ms per page (32 bytes), as specified in the AC Characteristics table of the Renesas datasheet. This self-timed duration applies to both individual byte writes and full-page programming. During this period, the WIP bit remains high, and the device ignores new instructions until completion - requiring host firmware to poll the status register before issuing subsequent commands.

Is the HN58X25128BTI#S0 compatible with 1.8 V microcontroller I/O interfaces?

Yes, the HN58X25128BTI#S0 operates across 1.8 V to 5.5 V and supports 3 MHz SPI communication at 1.8 V supply. Its VIH and VIL thresholds scale with VCC (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC), ensuring reliable logic-level recognition when interfaced directly with 1.8 V GPIOs. No external level shifters are needed, simplifying design for ultra-low-power sensor nodes and portable equipment.
