The AT24C32C/64C is 32,768/65,536 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 4096/8192 words of 8 bits each. The device’s cascadable feature allows up to 8 devices to share a common 2- wire bus. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential.

The document describes the features and characteristics of the AT24C1024B product, including low-voltage operation, internal organization, two-wire serial interface, Schmitt triggers, filtered inputs, bidirectional data transfer protocol, different clock rates, hardware and software data protection, page write mode, random and sequential read modes, self-timed write cycle, high reliability, etc.

AT49BV163D(T) is a 2.7-volt 16-megabit Flash memory with features such as single voltage read/write operation, fast read access time, sector erase architecture, fast program and erase time.

AT93C46D is a 1024-bit serial electrically erasable programmable read-only memory (EEPROM), organized as 64 words of 16 bits each (when the ORG pin is connected to VCC), and 128 words of 8 bits each (when the ORG pin is tied to ground). The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operations are essential. AT93C46D is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin mini-MAP (MLP 2x3), 8-lead TSSOP, and 8-lead dBGA2 packages. AT93C46D is enabled through the Chip Select pin (CS) and accessed via a three-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK). Upon receiving a Read instruction at DI, the address is decoded and the data is clocked out serially on the DO pin. The Write cycle is completely self-timed, and no separate Erase cycle is required before Write. The Write cycle is only enabled when the part is in the Erase/Write state.

AT49BV322D(T) is a 2.7V 32-megabit Flash memory organized as 2,097,152 words of 16 bits each or 4,194,304 bytes of 8 bits each. The x16 data appears on I/O0 - I/O15; the x8 data appears on I/O0 - I/O7. The memory is divided into 71 sectors for erase operations. The device is offered in a 48-lead TSOP and a 48-ball CBGA package. The device has CE and OE control signals to avoid any bus contention. This device can be read or reprogrammed using a single power supply, making it a reliable and compact solution with excellent performance and cost-effectiveness.

AT45DB161D is a 2.5-volt or 2.7-volt, serial-interface sequential access Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. The AT45DB161D supports RapidS serial interface for application-specific fast data transfer, provides flexible erase options, offers low power dissipation and high data retention, and supports hardware and software data protection.

The document describes the features and characteristics of a product, including the ARM7TDMI ARM Thumb processor, internal high-speed flash and SRAM, memory controller, and reset controller.

AT29C020 is a 5-volt-only in-system Flash programmable and erasable read-only memory (PEROM) manufactured by Atmel. It has 2 megabits of memory organized as 262,144 bytes. The device offers access times to 70 ns with power dissipation of just 220 mW over the commercial temperature range. When the device is deselected, the CMOS standby current is less than 100 µA. Device endurance is such that any sector can typically be written to in excess of 10,000 times. To allow for simple in-system reprogrammability, the AT29C020 does not require high input voltages for programming. Five-volt-only commands determine the operation of the device. Reading data out of the device is similar to reading from an EPROM. Reprogramming the AT29C020 requires the use of special commands, which are explained in this document.
