24LC256-I/SN

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

The Microchip Technology Inc. 25AA320/25LC320/25C320 (25XX320*) serial Electrically Erasable PROMs are 32 Kbit. A basic Serial Peripheral Interface (SPI) compliant serial bus is used to access the memory. A clock input (SCK) is required, as well as separate data in (SI) and data out (SO) lines. A Chip Selection (CS) input controls access to the device. The hold pin allows you to suspend communication with the gadget (HOLD). Transitions on the device's inputs will be ignored while it is stopped, excluding Chip Select, enabling the host to service higher priority interrupts. Features ? CMOS Low-Power Technology: - Maximum write current: 3 mA - Typical read current: 500 A - Typical standby current: 500 nA ? 4096 x 8 Bit Storage ? 32 bytes each page ? Maximum Write Cycle Time: 5 ms ? Erase and write cycles that are self-timed ? Write Block Protection: - Protect none, 1/4, 1/2, or the entire array. ?
