M27C1001-12F1

The M27C1001-12F1 is a 1 Megabit (128K x 8) CMOS EPROM, a type of non-volatile memory chip used primarily for storing firmware or software in electronic devices. It is manufactured by STMicroelectronics. The chip features a 120ns access time, enabling relatively quick data retrieval. It operates on a single 5V power supply, making it compatible with a variety of systems.
One of its key characteristics is that it is erasable with ultraviolet (UV) light, allowing for reprogramming. This is achieved by exposing the chip's quartz window to UV light, which clears the stored data, after which it can be reprogrammed using a suitable EPROM programmer.
The M27C1001-12F1 is housed in a 32-pin Dual In-line Package (DIP), which is common for ease of integration into circuit boards. It is ideal for applications that require data to be preserved even when the device is powered off, such as in embedded systems, microcontrollers, and other digital electronic devices where firmware updates are occasionally needed.

The M27C1001-12F1 is a 1Mb (128K x 8) UV EPROM chip. Equivalent products include the AT27C010 from Atmel, the AM27C010 from AMD, and the TMS27C010 from Texas Instruments. These chips have similar specifications in terms of storage capacity, functionality, and package types, making them suitable substitutes for applications requiring EPROM technology.

The M27C1001-12F1 is a 1 Megabit (128K x 8) UV EPROM. It comes in a 32-pin Dual in-line Package (DIP). Here is a brief overview of its pin count and functions:
- Power and Ground: VCC (Pin 30) is the power supply, and VSS (Pin 16) is the ground.
- Address Inputs: A0 to A16 (Pins 1-15 and 23) are used to address the memory locations.
- Data Outputs: Q0 to Q7 (Pins 11, 13, 14, 15, 17, 18, 19, 20) provide the data output.
- Control Pins:
- OE (Output Enable): Pin 22, enables data output buffers.
- CE (Chip Enable): Pin 20, activates the chip.
- Programming Pin: VPP (Pin 1) is used for the programming voltage during the programming phase.
This EPROM is mainly used for storing permanent data that can be erased via UV light exposure and reprogrammed.
