EPROM OTP 1M-Bit 128K x 8 90ns 32-Pin PLCC

The AT27BV010 is a high-performance, low-power, low-voltage 1,048,576-bit, onetime programmable, read-only memory (OTP EPROM) organized as 128K by 8 bits. It requires only one supply in the range of 2.7V to 3.6V in normal read mode operation, making it ideal for fast, portable systems using either regulated or unregulated battery power. The innovative design techniques provide fast speeds that rival 5V parts, while keeping the low power consumption of a 3V supply. At VCC = 2.7V, any byte can be accessed in less than 90ns. With a typical power draw of only 18mW at 5MHz and VCC = 3V, the AT27BV010 consumes less than one-fifth the power of a standard, 5V EPROM. Standby mode supply current is typically less than 1µA at 3V. The AT27BV010 simplifies system design and stretches battery lifetime even further by eliminating the need for power supply regulation. The AT27BV010 is available in an industry-standard, JEDEC-approved, one-time programmable (OTP) PLCC package. All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention.
