M87C257-15C1 Application Field and Working Principle

M87C257-15C1 is an 8-bit non-volatile memory chip that combines 8K bytes of FLASH memory and 5K bytes of OTP (One-Time Programming) memory. This chip is mainly used in OTP application fields where EEPROM memory needs to be maintained and low power consumption needs to be achieved.

M87C257-15C1 Chips fabricated with modern CMOS process have the characteristics of low power consumption and fast speed. At the same time, the operating current is only 3.2mA and the standby current is as low as 0.7mA, which greatly reduces the scope of power consumption.

The M87C257-15C1 Chip is divided into two parts, Flash memory and OTP memory. The Flash memory has the same characteristics, operations and functions as the conventional Flash memory. It can be erased in the whole chip, erasing all 8K bytes of storage areas in one time. OTP memory, which is one-time programming, allows parameters to be modified without affecting the original data so as to fully meet user requirements.

The operation of M87C257-15C1 can be divided into two parts: read and program. When reading, the M87C257-15C1 chip may be directly read like a ROM. This operation is similar to reading a ROM and the retrieved data is always valid. The actual life cycle depends on the next operation, the programming of the chip. When programming, the data of the chip is initialized and programmed. When programming is completed, the data of the corresponding area is permanently recorded onto the chip, and the chip is sent to the actual application.

M87C257-15C1 is widely used in application fields where EEPROM memory needs to be maintained and low power consumption needs to be achieved, such as automatic testing equipment, communication meter reading equipment, anti-theft alarm system, etc. It records data such as voltage, current values and serial numbers within equipments, mainly realizes user-specific programming, eliminates the cost of burning ROM, and provides users with high-integrity and low-cost programmable memories.
