Key Features
- 8 Mbit UVPROM density organized as 1M x 8, providing ample code storage for legacy embedded and industrial systems
- 100 ns maximum access time enabling fast random reads compatible with classic microprocessor bus cycles
- 32-pin ceramic DIP package (CDIP-32) with UV window for in-field erasure and reprogramming during development
Applications
The M27C801-100F6 is widely deployed in industrial controllers, legacy embedded systems, and prototype development environments where UV-erasable reprogrammable memory is needed for firmware storage. Its 1M x 8-bit organization and 100 ns access time make it compatible with a broad range of classic 8-bit and 16-bit microprocessor bus architectures. The ceramic DIP package with UV window is favored for engineering prototypes that require multiple erase-and-reprogram cycles during development.

Frequently Asked Questions
What read access time does the M27C801-100F6 offer, and which microprocessor bus speeds is it compatible with?
The M27C801-100F6 provides a maximum access time of 100 ns, making it compatible with classic 8-bit and 16-bit microprocessor buses running at up to 10 MHz. This performance level supports direct bus-attached code execution in industrial controllers and legacy embedded systems without requiring additional wait states in many designs.
How is the M27C801-100F6 memory organized, and how much data can it store?
The M27C801-100F6 is organized as 1,048,576 words of 8 bits each, giving a total density of 8 Mbits (1 MB). This organization is directly compatible with standard byte-wide memory interfaces, allowing firmware images up to 1 MB to be stored and accessed at 100 ns speeds on conventional parallel bus systems.
When is the M27C801-100F6 CDIP-32 package preferred over a PLCC or TSOP alternative for EPROM applications?
The 32-pin ceramic DIP (CDIP-32) package of the M27C801-100F6 is preferred in prototype and low-volume production environments because it accepts standard DIP sockets, enabling quick insertion and removal for UV erase cycles. For high-reliability industrial or military applications requiring ceramic hermetic packaging, CDIP also offers superior moisture resistance compared to plastic TSOP or PLCC alternatives.
How does the UV erase capability of M27C801-100F6 benefit hardware development compared to OTP devices?
Unlike one-time-programmable (OTP) EPROMs, the M27C801-100F6 can be erased using UV light at 253.7 nm for approximately 15 to 20 minutes and reprogrammed repeatedly. This allows engineers to iterate through multiple firmware versions during development without discarding devices, reducing prototype costs significantly when code changes are frequent across development cycles.
