Product details
Overview
M27V160-10XB1 from STMicroelectronics is a 16 Mbit low-voltage UV/OTP EPROM organized as 2 Mb × 8 or 1 Mb × 16, featuring 100 ns access time, 3 V–3.6 V read supply, and dual-mode byte/word configuration via BYTEVPP pin. It supports TTL-compatible control (E, G), electronic signature (20h/B1h), and operates in microprocessor-based program/data storage systems requiring nonvolatile, field-erasable (UV) or one-time programmable (OTP) memory.
For engineers reviewing the M27V160-10XB1 datasheet, M27V160-10XB1 pinout, M27V160-10XB1 application, or M27V160-10XB1 equivalent, key selection criteria include UV erasability vs. OTP packaging options, BYTEVPP-configurable data width, 12.5 V programming voltage with Presto III algorithm, and compatibility with legacy M27C160 programmers and 16 Mbit mask ROM footprints.
Technical Context
The M27V160-10XB1 implements a two-line output control architecture (E for chip enable/power gating, G for output enable), enabling low-power standby (60 µA) and eliminating bus contention in multi-device memory arrays. Its BYTEVPP pin selects between word-wide (Q15A–1 = Q15) and byte-wide (Q15A–1 = A–1) operation, with A–1 determining upper/lower byte selection in byte mode.
Programming uses 12.5 V ± 0.25 V on VPP and 6.25 V ± 0.25 V on VCC, applying 50 µs pulses per word under Presto III algorithm with margin-mode verify at elevated VCC. Electronic signature (A9 = 12 V, Q7–Q0 outputting 20h/B1h) enables automatic programmer identification, while UV erasure requires ≥30 W·sec/cm² at 2537 Å wavelength.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Capacity | 16 Mbit (2 Mb × 8 or 1 Mb × 16); enables direct replacement of 16 Mbit mask ROMs in legacy embedded systems. |
| Access Time | 100 ns; ensures compatibility with 8 MHz microprocessor buses without wait states. |
| Read Supply Voltage | 3.0 V–3.6 V; reduces system power consumption versus 5 V EPROMs, extending battery life in portable designs. |
| Programming Voltage | VPP = 12.5 V ± 0.25 V, VCC = 6.25 V ± 0.25 V; matches M27C160 programmer hardware, avoiding equipment upgrades. |
| Standby Current | 60 µA at VCC ≤ 3.6 V; minimizes quiescent power in always-on memory subsystems. |
| Electronic Signature | Manufacturer Code = 20h, Device Code = B1h; enables automated device recognition in production programming fixtures. |
| UV Erase Dose | ≥30 W·sec/cm² at 2537 Å; defines minimum exposure for full bit reset in FDIP42W windowed package. |
Pinout & Package
Package: FDIP42W (42-pin ceramic frit-seal DIP with UV-transparent window), PDIP42, SDIP42, PLCC44, or SO44 - all ECOPACK® (lead-free) compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 16 Mbit addressing; A–1 function reused on Q15A–1 in byte mode. |
| Q0–Q7 | Data Outputs (Lower Byte) | Active in both word and byte modes; deliver lower 8 bits when BYTEVPP = VIL and A–1 = VIL. |
| Q8–Q14 | Data Outputs (Upper Byte, Bits 8–14) | Deliver upper 7 bits of 16-bit word; Q15 delivered via Q15A–1 when BYTEVPP = VIH. |
| Q15A–1 | Configurable Terminal | Q15 output in word mode (BYTEVPP = VIH); A–1 address input in byte mode (BYTEVPP = VIL). |
| E | Chip Enable | Primary device select and power gate; VIH places device in standby (60 µA), eliminating leakage in deselected chips. |
| G | Output Enable | Secondary output control; allows shared G-bus across memory array while E manages individual chip power. |
| BYTEVPP | Mode Configuration / Program Supply | VIH selects word-wide mode and enables VPP path; VIL selects byte-wide mode and disables VPP connection. |
| VCC | Read/Verify Supply | 3.0–3.6 V for read; 6.25 V ± 0.25 V for programming/verify - requires dual-rail supply design. |
| VPP | Programming Supply Input | 12.5 V ± 0.25 V applied only during programming; internally disconnected in read/standby modes. |
| A9 | Electronic Signature Trigger | Receives 12 V ± 0.5 V to activate signature mode; outputs manufacturer/device codes on Q7–Q0. |
Key Features
| Feature | Design Value |
|---|---|
| Byte/Word Configurability | Single pin (BYTEVPP) switches between 8-bit and 16-bit data interface, simplifying PCB reuse across memory-width variants. |
| Presto III Programming | Guaranteed margin programming with 50 µs pulses and auto-verify at elevated VCC, eliminating overprogram risk and reducing cycle time. |
| Two-Line Output Control | Independent E (power) and G (output) enables zero-bus-contention memory expansion and <20 µA standby per deselected device. |
| Electronic Signature | Hardware-level device ID (20h/B1h) readable at A9 = 12 V, enabling unattended programming station validation and BOM traceability. |
| ECOPACK® Compliance | Lead-free packaging (PDIP42, PLCC44, SO44) meets RoHS and JEDEC JESD97 interconnect marking requirements. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M27C160-10F1 | 5 V core supply; no low-voltage read mode; identical pinout, programming algorithm, and 100 ns speed. | Requires 5 V system rail; incompatible with 3.3 V logic interfaces without level translation. | Select when legacy 5 V infrastructure exists and UV erasure is required with no voltage scaling constraints. |
| AT27C020-10PU | 2 Mbyte (16 Mbit) capacity; 5 V only; 100 ns access; different pinout (PLCC32/SO28); no BYTEVPP configurability. | Lacks byte/word mode switching; requires PCB redesign; no electronic signature support. | Select only for cost-sensitive replacements where board layout change is acceptable and dual-width flexibility is unnecessary. |
Compared with M27V160-10XB1, M27C160-10F1 sacrifices low-voltage operation for broader 5 V ecosystem compatibility, while AT27C020-10PU abandons configurability and signature features to reduce package size - making M27V160-10XB1 uniquely suited for voltage-scalable, field-upgradable, and production-automated EPROM deployments.

FAQ
Is M27V160-10XB1 still in production?
No - M27V160-10XB1 is an obsolete STMicroelectronics part, last manufactured in 2006. Aetrix Electronics maintains legacy inventory and offers traceable, tested units with full lot documentation for continued support of end-of-life systems.
What packages are available for M27V160-10XB1?
The "B1" suffix denotes the PDIP42 (plastic DIP, 42-pin, 600-mil width) package. Other valid packages include FDIP42W (ceramic UV-erasable), SDIP42 (shrink DIP), PLCC44, and SO44 - all ECOPACK® lead-free compliant per ordering code conventions in ST's datasheet Table 16.
Can M27V160-10XB1 be programmed on standard M27C160 programmers?
Yes - it uses identical Presto III programming algorithm, 12.5 V VPP, 6.25 V VCC, and 50 µs pulse timing. No hardware or software modification is needed; the device responds to the same command sequences and electronic signature (20h/B1h) as M27C160.
How does BYTEVPP affect memory organization and pin usage?
When BYTEVPP = VIH, the device operates in 16-bit word mode: Q15A–1 functions as Q15 output, and all Q0–Q15 are active. When BYTEVPP = VIL, it operates in 8-bit byte mode: Q15A–1 becomes A–1 address input, and Q8–Q14/Q0–Q7 serve as upper/lower byte outputs - enabling flexible data bus interfacing without external multiplexing.
