Manufactured with Atmel’s advanced nonvolatile CMOS technology, the devices offer access times to 90 ns with power dissipation of just 275 mW. When deselected, the CMOS standby current is less than 100 µA. The device contains a user-enabled “boot block” protection feature. Two versions of the feature are available: the AT49F008A/8192A locates the boot block at lowest order addresses (“bottom boot”); the AT49F008AT/8192AT locates it at highest order addresses (“top boot”). To allow for simple in-system reprogrammability, the AT49F008A(T)/8192A(T) does not require high-input voltages for programming. Reading data out of the device is similar to reading from an EPROM; it has standard CE, OE and WE inputs to avoid bus contention. Reprogramming the AT49F008A(T)/8192A(T) is performed by first erasing a block of data and then programming on a byte-by-byte or word-by-word basis.

The device is erased by executing the Erase command sequence; the device internally controls the erase operation. The memory is divided into four blocks for erase operations. There are two 4K word parameter block sections: the boot block, and the main memory array block. The typical number of program and erase cycles is in excess of 10,000 cycles. The optional 8K word boot block section includes a reprogramming lockout feature to provide data integrity. This feature is enabled by a command sequence. Once the boot block programming lockout feature is enabled, the data in the boot block cannot be changed when input levels of 5.5 2 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 volts or less are used. The boot sector is designed to contain user secure code. For the AT49F8192A(T), the BYTE pin controls whether the device data I/O pins operate in the byte or word configuration. If the BYTE pin is set at a logic “1” or left open, the device is in word configuration, I/O0 - I/O15 are active and controlled by CE and OE. If the BYTE pin is set at logic “0”, the device is in byte configuration, and only data I/O pins I/O0 - I/O7 are active and controlled by CE and OE. The data I/O pins I/O8 - I/O14 are tri-stated and the I/O15 pin is used as an input for the LSB (A-1) address function.

When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the outputs. The outputs are put in the highimpedance state whenever CE or OE is high. This dual line control gives designers flexibility in preventing bus contention. COMMAND SEQUENCES: When the device is first powered on, it will be reset to the read or standby mode, depending upon the state of the control line inputs. In order to perform other device functions, a series of command sequences are entered into the device. The command sequences are shown in the Command Definitions table (I/O8 - I/O15 are don’t care inputs for the command codes). The command sequences are written by applying a low pulse on the WE or CE input with CE or WE low (respectively) and OE high. The address is latched on the falling edge of CE or WE, whichever occurs last. The data is latched by the first rising edge of CE or WE. Standard microprocessor write timings are used. The address locations used in the command sequences are not affected by entering the command sequences. 3 1199F–04/01 RESET: A RESET input pin is provided to ease some system applications. When RESET is at a logic high level, the device is in its standard operating mode. A low level on the RESET input halts the present device operation and puts the outputs of the device in a high-impedance state. When a high level is reasserted on the RESET pin, the device returns to the read or standby mode, depending upon the state of the control inputs. By applying a 12V ± 0.5V input signal to the RESET pin, the boot block array can be reprogrammed even if the boot block program lockout feature has been enabled (see Boot Block Programming Lockout Override section). ERASURE: Before a byte or word can be reprogrammed, it must be erased. The erased state of memory bits is a logic “1”. The entire device can be erased by using the Chip Erase command or individual sectors can be erased by using the Sector Erase command. CHIP ERASE: The entire device can be erased at one time by using the 6-byte chip erase software code. After the chip erase has been initiated, the device will internally time the erase operation so that no external clocks are required. The maximum time to erase the chip is tEC. If the boot block lockout has been enabled, the chip erase will not erase the data in the boot block; it will erase the main memory block and the parameter blocks only. After the chip erase, the device will return to the read or standby mode. SECTOR ERASE: As an alternative to a full chip erase, the device is organized into four sectors that can be individually erased. There are two 4K word parameter block sections, one boot block, and the main memory array block. The Sector Erase command is a six-bus cycle operation. The sector address is latched on the falling WE edge of the sixth cycle while the 30H data input command is latched at the rising edge of WE. The sector erase starts after the rising edge of WE of the sixth cycle. The erase operation is internally controlled; it will automatically time to completion. Whenever the main memory block is erased and reprogrammed, the two parameter blocks should be erased and reprogrammed before the main memory block is erased again. Whenever a parameter block is erased and reprogrammed, the other parameter block should be erased and reprogrammed before the first parameter block is erased again. Whenever the boot block is erased and reprogrammed, the main memory block and the parameter blocks should be erased and reprogrammed before the boot block is erased again. BYTE/WORD PROGRAMMING: Once a memory block is erased, it is programmed (to a logic “0”) on a byte-by-byte or word-by-word basis. Programming is accomplished via the internal device command register and is a four-bus cycle operation. The device will automatically generate the required internal program pulses. 4 Any commands written to the chip during the embedded programming cycle will be ignored. If a hardware reset happens during programming, the data at the location being programmed will be corrupted. Please note that a data “0” cannot be programmed back to a “1”; only erase operations can convert “0”s to “1”s. Programming is completed after the specified tBP cycle time. The Data Polling feature may also be used to indicate the end of a program cycle. BOOT BLOCK PROGRAMMING LOCKOUT: The device has one designated block that has a programming lockout feature. This feature prevents programming of data in the designated block once the feature has been enabled. The size of the block is 8K words. This block, referred to as the boot block, can contain secure code that is used to bring up the system. Enabling the lockout feature will allow the boot code to stay in the device while data in the rest of the device is updated. This feature does not have to be activated; the boot block’s usage as a write-protected region is optional to the user. The address range of the boot block is 00000H to 03FFFH for the AT49F008A; FC000H to FFFFFH for the AT49F008AT; 00000H to 01FFFH for the AT49F8192A; and 7E000H to 7FFFFH for the AT49F8192AT. Once the feature is enabled, the data in the boot block can no longer be erased or programmed when input levels of 5.5V or less are used. Data in the main memory block can still be changed through the regular programming method. To activate the lockout feature, a series of six program commands to specific addresses with specific data must be performed. Please refer to the Command Definitions table. BOOT BLOCK LOCKOUT DETECTION: A software method is available to determine if programming of the boot block section is locked out. When the device is in the software product identification mode (see Software Product Identification Entry and Exit sections), a read from the following address location will show if programming the boot block is locked out – 00002H for the AT49F008A and AT49F8192A; FC002H for the AT49F008AT; and 7E002H for the AT49F8192AT. If the data on I/O0 is low, the boot block can be programmed; if the data on I/O0 is high, the program lockout feature has been enabled and the block cannot be programmed. The software product identification exit code should be used to return to standard operation. BOOT BLOCK PROGRAMMING LOCKOUT OVERRIDE: The user can override the boot block programming lockout by taking the RESET pin to 12 volts during the entire chip erase, sector erase or word programming operation. When the RESET pin is brought back to TTL levels, the boot block programming lockout feature is again active. PRODUCT IDENTIFICATION: The product identification mode identifies the device and manufacturer as Atmel. It may be accessed by hardware or software operation. The AT49F008A(T)/8192A(T) 1199F–04/01 AT49F008A(T)/8192A(T) hardware operation mode can be used by an external programmer to identify the correct programming algorithm for the Atmel product. For details, see “Operating Modes” (for hardware operation) or “Software Product Identification Entry/Exit” on page 12. The manufacturer and device codes are the same for both modes. DATA POLLING: The AT49F008A(T)/8192A(T) features Data Polling to indicate the end of a program cycle. During a program cycle an attempted read of the last byte loaded will result in the complement of the loaded data on I/O7. Once the program cycle has been completed, true data is valid on all outputs and the next cycle may begin. During a chip or sector erase operation, an attempt to read the device will give a “0” on I/O7. Once the program or erase cycle has completed, true data will be read from the device. Data Polling may begin at any time during the program cycle. TOGGLE BIT: In addition to Data Polling, the AT49F008A(T)/8192A(T) provides another method for determining the end of a program or erase cycle. During a program or erase operation, successive attempts to read data from the device will result in I/O6 toggling between one and zero. Once the program cycle has completed, I/O6 will stop toggling and valid data will be read. Examining the toggle bit may begin at any time during a program cycle. READY/BUSY: For the AT49F008A(T), pin 12 is an open-drain Ready/Busy output pin, which provides another method of detecting the end of a program or erase operation. RDY/BUSY is actively pulled low during the internal program and erase cycles and it is released at the completion of the cycle. The open-drain connection allows for OR-tying of several devices to the same RDY/BUSY line. HARDWARE DATA PROTECTION: Hardware features protect against inadvertent programs to the AT49F008A(T)/8192A(T) in the following ways: (a) VCC sense: if VCC is below 3.8V (typical), the program function is inhibited. (b) VCC power-on delay: once VCC has reached the VCC sense level, the device will automatically time-out 10 ms (typical) before programming. (c) Program inhibit: holding any one of OE low, CE high or WE high inhibits program cycles. (d) Noise filter: pulses of less than 15 ns (typical) on the WE or CE inputs will not initiate a program cycle. 5 1199F–04/01 Command Definition in Hex(1) Command Sequence 1st Bus Cycle Bus Cycles Addr Data Read 1 Addr DOUT Chip Erase 6 5555 AA 2nd Bus Cycle 3rd Bus Cycle 4th Bus Cycle Data Addr Data Addr Data Addr Data Addr Data 2AAA 55 5555 80 5555 AA 2AAA 55 5555 10 2AAA 55 (4) SA 30 2AAA 55 5555 40 6 5555 AA 2AAA 55 5555 80 5555 AA Byte/Word Program 4 5555 AA 2AAA 55 5555 A0 Addr DIN Boot Block Lockout(2) 6 5555 AA 2AAA 55 5555 80 5555 AA Product ID Entry 3 5555 AA 2AAA 55 5555 90 (3) 3 5555 AA 2AAA 55 5555 F0 (3) 1 xxxx F0 Product ID Exit Notes: 6th Bus Cycle Addr Sector Erase Product ID Exit 5th Bus Cycle 1.
