M25P40-VMN6TPB

The Serial Electrically-Erasable Programmable Read-Only Memory (EEPROM) on the Atmel® AT25320B/640B has 32,768-/65,536-bits and is divided into 4,096/8,192 words with 8 bits each. The device is prepared for usage in a wide range of industrial and commercial settings where moderate and low-voltage functioning are critical requirements. The 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead UDFN, 8-lead XDFN, and 8-ball VFBGA packages for the AT25320B/640B are available in compact sizes. A 3-wire interface made up of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock is used to access and enable the AT25320B/640B. (SCK). No further erase cycle is necessary before Write since every programming cycle is fully self-timed. Programming one of the four blocks of write security into the status register activates block write protection. For added data security, separate instructions for programme enable and programme disable are given. The WP pin offers hardware data protection to guard against unintentional write attempts to the status register. Any serial communication can be halted using the HOLD pin without having to restart the serial sequence.

A 4K x 8 (32K bit) Serial Electrically Erasable PROM is the 24C32. This gadget was created for high-end, low-power uses like data collecting or personal communications. The 24C32 has an input cache with a capacity of eight 8-byte pages, or 64 bytes, allowing quick write loads. Additionally, it has a fixed 4K-bit block of ultra-high endurance memory for regularly changing data. Up to the 32K border, the 24C32 may read both randomly and sequentially. Up to eight 24C32 devices can share a bus with functional address lines, providing a maximum address space of 256K bits. This device is perfect for moderate POWER  non-volatile code and data applications thanks to advanced CMOS technology. The typical 8-pin plastic DIP and 8-pin surface mount SOIC packaging for the 24C32 are also available.   Features:- • Operating voltage range: 4.5V to 5.5V - Maximum read current: 150 A at 5.5V - Peak write current: 3mA at 5.5V - Typical standby current: 1 A • I2C compliant, industry-standard two-wire bus protocol with 100 kHz and 400 kHz modes • Autonomous write cycle (including auto-erase) • Switchable circuitry for data protection • High Endurance Block has a guaranteed 10,000,000 Erase/Write cycles. - Guaranteed 1,000,000 E/W cycles for Standard Endurance Block • Available in 8 byte page or byte modes. • A 64-byte input cache with 1 page by 8 lines for quick write loads. • Schmitt trigger with filtered inputs to reduce noise • Ground bounce elimination by output slope control • A typical write cycle time, byte or page, of 2 ms • A single bus may support up to 8 chips and 256K bits of total memory. • Protection from electrostatic discharge > 4000V • 200-year data retention • PDIP/SOIC 8-pin packages • Variable temperatures Industrial (I): -40°C to +85°C Commercial (C): 0°C to +70°C
