This document introduces the features and characteristics of the Microchip Technology Inc. 37LV36/65/128 series, including operational equivalence, voltage range, maximum read current, standby current, industry standard synchronous serial interface, full static operation, sequential read/programming, cascadable output enable, maximum clock rate, hardware reset programmable polarity, industry standard EPROM programmers programming, electrostatic discharge protection, package types, data retention time, and operating temperature range.
This manual describes the Microchip 37LV36/65/128 Serial EPROM family, covering 36 K, 64 K and 128 K devices. It outlines features such as a wide 3.0 V‑to‑6.0 V operating range, up to 10 mA read current, and standby current as low as 100 pA. The document includes electrical characteristics, pin functions, programming procedures, and cascading options for multiple EPROMs.
Technical data such as voltage ranges, temperature limits, maximum clock rates, and programming voltages are provided in detailed tables. Package options (8‑pin PDIP/SOIC and 20‑pin PLCC) and ordering information are also listed, along with worldwide sales and service contacts.

| Programming voltage VPP1 | 12.5 V to 13.5 V |
| Programming current | 100 mA |
| Package types | 8‑pin PDIP/SOIC, 20‑pin PLCC |
The devices operate from 3.0 V up to 6.0 V.
Standby current is typically 100 pA.
Commercial: 0 °C to +70 °C; Industrial: -40 °C to +85 °C.
Programming voltage VPP1 must be between 12.5 V and 13.5 V, with VPP2 tied to VCC.
