ATMEL Manuals

The document describes the features and characteristics of the AT27C080 chip, including fast read access time, low power CMOS operation, JEDEC standard packages, high-reliability CMOS technology, rapid programming algorithm, etc.

The AT24C256B is a serial EEPROM memory with features including low-voltage and standard-voltage operation, internally organized as 32,768 x 8, a two-wire serial interface, Schmitt trigger, filtered inputs for noise suppression, bidirectional data transfer protocol, etc.

The AT45DB041B is an SPI compatible serial interface Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applica- tions. Its 4,325,376 bits of memory are organized as 2048 pages of 264 bytes each. In addition to the main memory, the AT45DB041B also contains two SRAM data buffers of 264 bytes each. The buffers allow receiving of data while a page in the main memory is being repro- grammed, as well as reading or writing a continuous data stream. EEPROM emulation (bit or byte alterability) is easily handled with a self-contained three step Read-Modify- Write operation. Unlike conventional Flash memories that are accessed randomly with multiple pages, the AT45DB041B supports page programming, allowing programming or erasing a single page in a single clock cycle.

The AT28C256 is a high-performance electrically erasable and programmable read-only memory from Atmel. It features a 150ns read access time and 440mW power consumption. The device has 32768 8-bit words of 256KB of storage space and uses Atmel's advanced non-volatile CMOS technology. The AT28C256 can be accessed like a static random-access memory for reading or writing, without the need for external components. The device contains a 64-byte page register to allow simultaneous writing of up to 64 bytes of data. During a write cycle, the addresses and 1 to 64 bytes of data are internally latched, freeing the address and data bus for other operations. After the start of a write cycle, the device will automatically write the address and data to the memory.

The T7024 is a monolithic SiGe transmit/receive front-end IC with power amplifier, low-noise amplifier and T/R switch driver. It is especially designed for operation in TDMA systems like Bluetooth® and WDCT. Due to the ramp-control feature and a very low quiescent current, an external switch transistor for VS is not required.
