FAQs
What is TMS27PC256?
The TMS27PC256 is a 256 Kbit (32 Kbyte) UV erasable programmable read-only memory (EPROM) manufactured by Texas Instruments. It is designed for applications that require non-volatile storage of program code, configuration settings, or calibration data.
How Does TMS27PC256 Work?
The TMS27PC256 operates by storing binary data in memory cells that can be electrically programmed and erased using a UV light source. The stored data remains intact even when the power is turned off, making it suitable for long-term data storage in embedded systems and legacy devices.
How Many Pins does TMS27PC256 have and What are the Functions of the Pinout Configuration?
The TMS27PC256 is housed in a 28-pin DIP (Dual Inline Package) or a 32-pin PLCC (Plastic Leaded Chip Carrier) package. The pinout configuration includes:
- A0-A14: Address pins for selecting memory locations.
- DQ0-DQ7: Data input/output pins for reading from and writing to the memory.
- CE: Chip enable pin to activate the memory chip.
- OE: Output enable pin to enable the data output buffer.
- WE: Write enable pin for initiating write operations.
- VPP: Programming voltage pin for EPROM programming.
- VCC, GND: Power supply and ground pins.
What are the Pros and Cons of TMS27PC256?
Pros:
- Non-Volatile: Retains stored data without power, ensuring long-term reliability.
- UV Erasable: Can be electrically programmed and erased using UV light for reprogramming.
- Simple Interface: Utilizes standard address, data, and control pins for easy integration.
- Durable Packaging: Available in industry-standard DIP or PLCC packages for robust assembly.
Cons:
- UV Exposure Requirement: UV erasing process requires careful handling and additional equipment.
- Limited Endurance: Limited number of erase/write cycles compared to newer non-volatile memories.
- Obsolete Technology: As a UV EPROM, it may not be suitable for new designs requiring higher densities and faster access times.
Are There Any Equivalents/Alternatives to TMS27PC256 for Recommendation?
- The M27C256B from STMicroelectronics is an equivalent UV EPROM with similar capacity and functionality.
- Alternatives to the TMS27PC256 include modern non-volatile memories such as serial EEPROMs or Flash memories that offer higher densities and faster access times.
