Description and Introduction

131 072-Bit UV Erasable Programmable Read-Only Memory 28-CDIP The TMS27C128JL is a 128K (16K x 8) UV-erasable programmable read-only memory (EPROM) manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 16K x 8  
- **Speed:** 200 ns (access time)  
- **Supply Voltage:** 5V ± 10%  
- **Power Dissipation:**  
  - Active: 525 mW (max)  
  - Standby: 132 mW (max)  
- **Operating Temperature Range:**  
  - Commercial (0°C to 70°C)  
  - Industrial (-40°C to 85°C)  
- **Package Options:**  
  - 28-pin Ceramic DIP (Dual Inline Package)  
  - 28-pin Plastic DIP  
  - 28-pin PLCC (Plastic Leaded Chip Carrier)  

### **Descriptions:**
- The TMS27C128JL is a high-performance, electrically programmable read-only memory with UV-erasable capability.  
- It is designed for applications requiring non-volatile storage of firmware or data.  
- Data retention is guaranteed for at least 10 years.  

### **Features:**
- **UV-Erasable:** Can be erased by exposure to ultraviolet light for reprogramming.  
- **Single 5V Power Supply:** No additional voltages required for read operations.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Tri-State Outputs:** Allows for easy bus sharing in microprocessor systems.  
- **Programmable:** Supports standard EPROM programming methods.  
- **High Reliability:** Industrial-grade options available for harsh environments.  

This information is based on the manufacturer's datasheet for the TMS27C128JL.

Alternative Part Number

  • M27C128A-20F1 --: Pin-compatible 128Kbit (16K x 8) UV EPROM with similar access time and DIP-28 package, direct functional replacement.
  • M27C128B-25F1 --: Same 128Kbit EPROM density and pinout, slightly slower access time but widely available and electrically compatible.
  • HN27C128AG-20 --: Equivalent 128Kbit CMOS UV EPROM in DIP-28 with comparable speed and pinout, usable as a drop-in substitute.
  • M27C128A-15F1 --: Pin-compatible 128Kbit UV EPROM with similar access time and DIP package, widely available as a direct replacement.
  • HN27C128AG-15 --: Equivalent 128Kbit CMOS EPROM in 28-pin DIP with comparable speed and pinout, suitable for direct substitution.
  • MBM27C128-15 --: 128Kbit UV EPROM with matching organization and DIP footprint, a viable alternative when TI parts are unavailable.
  • M27C128B-15F1 --: Pin-compatible 128Kbit UV EPROM with similar access time and DIP package, widely available as a direct functional replacement.
  • NMC27C128BQ150 --: Equivalent 128Kbit CMOS EPROM in the same JEDEC pinout, suitable drop-in substitute for legacy designs.
