Product details
Overview
M27V160-100XF1 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 serves as a drop-in replacement for 16 Mbit mask ROMs in legacy microprocessor-based systems requiring nonvolatile program storage with field-erasable (UV) or one-time programmable (OTP) options.
For engineers reviewing the M27V160-100XF1 datasheet, M27V160-100XF1 pinout, M27V160-100XF1 application, or M27V160-100XF1 equivalent, key selection criteria include UV erasability vs. OTP packaging variants, BYTEVPP-configurable data width, 12.5 V programming voltage compatibility, and ECOPACK® lead-free package compliance per JEDEC JESD97.
Technical Context
The M27V160-100XF1 implements a two-line output control architecture with independent Chip Enable (E) and Output Enable (G), enabling low-power array expansion without bus contention. Its organization switching-Word-wide (Q15A–1 = data output) or Byte-wide (Q15A–1 = address A–1)-is determined solely by BYTEVPP logic level during read mode.
Programming follows the Presto III algorithm with 50 µs/word pulses at VCC = 6.25 V ± 0.25 V and VPP = 12.5 V ± 0.25 V; verify occurs under margin mode at elevated VCC to ensure cell programming robustness. Electronic signature (Manufacturer Code 20h, Device Code B1h) is accessed via 12 V on A9 with toggled A0, confirming identity for automated programmers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Capacity | 16 Mbit (2,097,152 × 8 or 1,048,576 × 16), enabling full firmware storage for 8-bit or 16-bit microcontrollers. |
| Access Time | 100 ns max at VCC = 3.3 V, supporting synchronous bus timing up to 8 MHz in legacy embedded systems. |
| Read Supply Voltage | 3.0 V–3.6 V, reducing active current to 30 mA at 8 MHz and extending battery life in portable industrial controllers. |
| Standby Current | 60 µA max, achieved when E = VIH, allowing deep sleep in power-constrained instrumentation. |
| Programming Voltage | VPP = 12.5 V ± 0.25 V, requiring dedicated high-voltage circuitry but ensuring compatibility with M27C160 programmers. |
| Programming Time | 50 µs per word, enabling full-array programming in ~52.5 s using Presto III algorithm with margin verification. |
| Electronic Signature | Manufacturer Code 20h (STMicroelectronics), Device Code B1h, readable via A9 = 12 V and A0 toggle for auto-algorithm selection. |
Pinout & Package
Package: FDIP42W (42-pin ceramic frit-seal DIP with UV window), RoHS-compliant ECOPACK® variant with lead-free terminations and JEDEC JESD97 second-level interconnect marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 16 Mbit addressing; A–1 function shared with Q15A–1 in Byte-wide mode. |
| Q0–Q7 | Data Outputs (Byte-wide) | Lower 8-bit data path when BYTEVPP = VIL and A–1 = VIL; TTL-compatible outputs. |
| Q8–Q14 | Data Outputs (Byte-wide Upper / Word-wide Lower) | Upper 7 bits of 16-bit word or upper byte segment; driven only when selected by BYTEVPP and A–1. |
| Q15A–1 | Configurable Terminal | Q15 output in Word-wide mode (BYTEVPP = VIH); A–1 address input in Byte-wide mode (BYTEVPP = VIL). |
| E | Chip Enable | Primary device select; VIH places device in standby (high-Z outputs), VIL enables memory array access. |
| G | Output Enable | Secondary output gate; controls data assertion independently of E, enabling shared bus arbitration. |
| BYTEVPP | Mode Select / Program Supply | VIH selects Word-wide mode and enables VPP path; VIL selects Byte-wide mode and disables VPP. |
| VCC | Read Supply | 3.0–3.6 V for read/standby; 6.25 V ± 0.25 V required only during programming. |
| VSS | Ground | Dual VSS pins (pins 16 & 32) provide low-inductance return paths for decoupling and noise reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Byte/Word Configurability | Single-pin (BYTEVPP) selection between 8-bit and 16-bit data interfaces, eliminating need for external multiplexing logic. |
| Two-Line Output Control | Independent E (power gating) and G (output gating) enable zero-bus-contention memory arrays with minimal standby current per device. |
| Presto III Programming | Guaranteed margin programming with automatic verify at elevated VCC, eliminating over-program risk and reducing test time. |
| UV Erasability (FDIP42W) | Quartz window allows full bit-pattern erasure in 30–40 min using 2537 Å UV lamp at ≥30 W·sec/cm² dose, supporting firmware iteration. |
| ECOPACK® Compliance | Lead-free construction with JEDEC JESD97 interconnect marking, meeting RoHS and industrial environmental requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar EPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM27C160-120DC | 5 V-only operation (no 3 V read), 120 ns access, UV-erasable ceramic DIP; lacks BYTEVPP configurability and ECOPACK®. | Requires 5 V system rail; incompatible with low-voltage microcontrollers; no byte/word mode flexibility. | Select only if legacy 5 V design mandates identical timing and footprint without low-voltage or configurability needs. |
| M27C160-120F1 | Same 5 V operation and 120 ns speed as AM27C160; shares identical electronic signature (20h/B1h) and Presto III programming. | Not rated for 3 V operation; higher active current (55 mA at 5 V) limits battery-powered use. | Choose when migrating from M27C160 and UV erasure is required, but 3 V compatibility is unnecessary. |
Compared with M27V160-100XF1, AM27C160-120DC offers higher voltage tolerance but sacrifices low-power operation and data-width flexibility, while M27C160-120F1 preserves programming compatibility at the cost of read voltage headroom and power efficiency.

FAQ
Is M27V160-100XF1 compatible with standard 5 V EPROM programmers?
No. The M27V160-100XF1 requires VCC = 6.25 V ± 0.25 V and VPP = 12.5 V ± 0.25 V during programming, matching the M27C160 specification. Standard 5 V programmers must be configured to deliver these exact voltages; using 5 V on VCC will fail programming verification.
What is the functional difference between FDIP42W and PDIP42 packages for this part?
FDIP42W features a quartz window for UV erasure and ceramic hermetic sealing, enabling multiple firmware revisions. PDIP42 is plastic-encapsulated and OTP-only-once programmed, contents cannot be erased. Both share identical pinout and electrical behavior in read mode.
Can BYTEVPP be left unconnected or tied to VCC/GND permanently?
No. BYTEVPP must be actively driven to VIH (≥2.0 V) for Word-wide mode or VIL (≤0.8 V) for Byte-wide mode. Floating or static bias risks undefined data width behavior, incorrect Q15A–1 functionality, and potential bus conflicts during read operations.
Does the 60 µA standby current apply across the full industrial temperature range?
Yes. The 60 µA maximum standby current is specified over TA = –40°C to +85°C per DC Characteristics Table 5. This value reflects worst-case leakage at elevated temperature and ensures reliable low-power operation in unregulated industrial environments.
