The Atmel AT45DB161E is a 2.3V or 2.5V minimum, serial-interface sequential access Flash memory ideally suited for a wide variety of digital voice, image, program code, and data storage applications. The AT45DB161E also supports RapidS serial interface for applications requiring very high speed operation. Its 17,301,504 bits of memory are organized as 4,096 pages of 512 bytes or 528 bytes each. In addition to the main memory, the AT45DB161E also contains two SRAM buffers of 512/528 bytes each. The buffers allow receiving of data while a page in the main memory is being reprogrammed. Interleaving between both buffers can dramatically increase a system's ability to write a continuous data stream. In addition, the SRAM buffers can be used as additional system scratch pademory, and E2PROM emulation bit or byte alterability can be easily handled with a self-contained three step read-modify-write operation.

Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the Atmel uses a serial interface to sequentially access its data. The simple sequential access dramatically reduces active pin count, facilitates simplified hardware layout, increases system reliability, minimizes switching noise, and reduces package size. The device is optimized for use in many commercial and industrial applications where high-density, low-pin count, low-voltage, and low-power are essential.

To allow for simple in-system re-programmability, the AT45DB161E does not require high input voltages for programming. The device operates from a single 2.3V to 3.6V or 2.5V to 3.6V power supply for the erase and program and read operations. The AT45DB161E is enabled through the Chip Select pin CS and accessed via a 3-wire interface consisting of the Serial Input SI , Serial Output SO , and the Serial Clock SCK .

All programming and erase cycles are self-timed.

Name and Function
Devices are initially shipped from Atmel with the buffer and page sizes set to 528 bytes. Devices can be ordered from Atmel pre-configured for the "power of 2" binary size of 512 bytes. For details, see Section Ordering Information on page

To configure the device for "power of 2" binary page size 512 bytes , a 4-byte opcode sequence of 3Dh, 2Ah, 80h, and A6h must be clocked into the device. After the last bit of the opcode sequence has been clocked in, the CS pin must be deasserted to initiate the internally self-timed configuration process and nonvolatile register program cycle. The programming of the nonvolatile register should take place in a time of tEP, during which time the RDY/BUSY bit in the Status Register will indicate that the device is busy. The device does not need to be power cycled after the completion of the configuration process and register program cycle in order for the buffer and page size to be configured to 512 bytes.

To configure the device for standard DataFlash page size 528 bytes , a 4-byte opcode sequence of 3Dh, 2Ah, 80h, and A7h must be clocked into the device. After the last bit of the opcode sequence has been clocked in, the CS pin must be deasserted to initial the internally self-timed configuration process and nonvolatile register program cycle. The programming of the nonvolatile register should take place in a time of tEP, during which time the RDY/BUSY bit in the Status Register will indicate that the device is busy. The device does not need to be power cycled after the completion of the configuration process and register program cycle in order for the buffer and page size to be configured to 528 bytes.

Manufacturer and Device ID Read

Identification information can be read from the device to enable systems to electronically query and identify the device while it is in the system. The identification method and the command opcode comply with the JEDEC Standard for “Manufacturer and Device ID Read Methodology for SPI Compatible Serial Interface Memory Devices”. The type of information that can be read from the device includes the JEDEC-defined Manufacturer ID, the vendor-specific Device ID, and the vendor-specific Extended Device Information.

The Read Manufacturer and Device ID command is limited to a maximum clock frequency of fCLK. Since not all Flash devices are capable of operating at very high clock frequencies, applications should be designed to read the identification information from the devices at a reasonably low clock frequency to ensure that all devices to be used in the application can be identified properly. Once the identification process is complete, the application can then increase the clock frequency to accommodate specific Flash devices that are capable of operating at the higher clock frequencies.

To read the identification information, the CS pin must first be asserted and then the opcode 9Fh must be clocked into the device. After the opcode has been clocked in, the device will begin outputting the identification data on the SO during the subsequent clock cycles. The first byte to be output will be the Manufacturer ID, followed by two bytes of the Device ID information. The fourth byte output will be the Extended Device Information EDI String Length, which will be 01h indicating that one byte of EDI data follows. After the one byte of EDI data is output, the SO pin will go into a high-impedance state therefore, additional clock cycles will have no affect on the SO pin and no data will be output. As indicated in the JEDEC Standard, reading the EDI String Length and any subsequent data is optional.

Deasserting the CS pin will terminate the Manufacturer and Device ID Read operation and put the SO pin into a high-impedance state. The CS pin can be deasserted at any time and does not require that a full byte of data be read.
