STMicroelectronics M95P08-IXMNT/E

Overview

M95P08-IXMNT/E from STMicroelectronics is an 8-Mbit serial SPI page EEPROM with dual/quad output capability, organized as 2048 × 512-byte pages and featuring two dedicated 512-byte identification pages. It operates from 1.6–3.6 V over –40 °C to +85 °C, supports up to 80 MHz clock frequency, delivers 320 Mbits/s quad-read throughput, and provides 500 kcycles write endurance with 100-year data retention.

For engineers reviewing the M95P08-IXMNT/E datasheet, M95P08-IXMNT/E pinout, M95P08-IXMNT/E application, or M95P08-IXMNT/E equivalent, key selection criteria include SPI dual/quad read timing, page-program latency (1.2 ms typ), ECC-enabled reliability (DEC/TED), block-level write protection, and ultra-low deep power-down current (0.6 μA typ).

Technical Context

The device implements a proprietary NVM architecture with integrated Program-Erase Controller (PEC) managing auto-erase-and-program cycles for byte/page writes, enabling flexible in-system data updates without full-chip erase. Its memory map supports hierarchical erasure-page (512 B), sector (4 KB), block (64 KB), or chip-wide-with configurable protection via non-volatile status register bits (BPn/TB).

Quad/dual-output read modes use D-DQ0, Q-DQ1, W-DQ2, and HOLD-DQ3 as bidirectional I/Os during fast-read commands, while retaining standard SPI MOSI/MISO nomenclature in single-mode operation. ECC logic operates transparently across all reads, delivering double-bit correction and triple-bit detection over 16-byte chunks without software intervention.

FAQ

What SPI modes does the M95P08-IXMNT/E support?

The device supports CPOL = 0, CPHA = 0 and CPOL = 1, CPHA = 1 SPI modes. Input data is latched on the rising edge of the serial clock (C), and output data appears on the falling edge. The polarity difference affects idle clock state only - both modes ensure compatibility with most ARM Cortex-M and Renesas RX-series MCUs without hardware modification.

How does the ECC function impact system-level reliability?

ECC operates transparently on every read, correcting up to two bit errors per 16-byte chunk and detecting three-bit errors. Corrected errors are logged in the safety register, enabling predictive maintenance. This eliminates silent data corruption in safety-critical applications such as medical device calibration storage or automotive ECU configuration.

Can the two identification pages be used simultaneously for UID and secure parameter storage?

Yes: the first 512-byte ID page contains factory-assigned identification data and can be provisioned with a unique ID upon request; the second 512-byte ID page is user-writable and supports permanent read-only locking via software command - ideal for storing cryptographic keys or regulatory audit logs that must never be altered post-deployment.

What is the minimum VCC ramp rate required during power-up?

No minimum ramp rate is specified, but VCC must rise continuously from 0 V to ≥1.6 V before the first falling edge on chip select (S). The internal POR circuit activates once VCC exceeds its threshold (lower than 1.6 V), ensuring reliable reset. A pull-up resistor on S (e.g., 100 kΩ to VCC) guarantees proper sequencing and prevents floating states during ramp-up.
