Writing or erasing the device is done with a single 5 Volt power supply. The device has separate chip enable CE, write enable WE , and output enable OE controls to eliminate bus contention. The V29C51002T/V29C51002B offers a combination of: Boot Block with Sector Erase/Write Mode. The end of write/erase cycle is detected by DATA Polling of I/O7 or by the Toggle Bit I/O6. The V29C51002T/V29C51002B features a sector erase operation which allows each sector to be erased and reprogrammed without affecting data stored in other sectors. The device also supports full chip erase. Boot block architecture enables the device to boot from a protected sector located either at the top (V29C51002T) or the bottom (V29C51002B). All inputs and outputs are CMOS and TTL compatible. The V29C51002T/V29C51002B is ideal for applications that require updatable code and data storage. s Device Usage Chart Operating Temperature Range 0°C to 70°C Package Outline P • T • J • Access Time (ns) 55 • 90 • Temperature Mark Blank V29C51002T/V29C51002B Rev. 2.1 October 2000 1 MOSEL VITELIC V29C51002T/V29C51002B V 29 C 51 002 T – OPERATING VOLTAGE 51: 5V DEVICE 55: 55ns 90: 90ns SPEED P = PDIP T = TSOP-I J = PLCC PKG.

The 16 KB lockable Boot Block is intended for storage of the system BIOS boot code. The boot code is the first piece of code executed each time the system is powered on or rebooted. The V29C51002 is available in two versions: the V29C51002T with the Boot Block address starting from 3C000H to 3FFFFH, and the V29C51002B with the Boot Block address starting from 00000H to 3FFFFH. V29C51002T 16KB Boot Block 512 Byte 512 Byte V29C51002T/V29C51002B V29C51002B 3FFFFH 3C000H 512 Byte 512 Byte 03FFFH 512 Byte 00000H 00000H 512 Byte 16KB Boot Block 51002-15 Read Cycle A read cycle is performed by holding both CE and OE signals LOW. Data Out becomes valid only when these conditions are met. During a read cycle WE must be HIGH prior to CE and OE going LOW. WE must remain HIGH during the read operation for the read to complete (see Table 1). 16KB Boot Block = 32 Sectors Byte Write Cycle The V29C51002T/V29C51002B is programmed on a byte-by-byte basis. The byte write operation is initiated by using a specific four-bus-cycle sequence: two unlock program cycles, a program setup command and program data program cycles (see Table 2). During the byte write cycle, addresses are latched on the falling edge of either CE o r WE, whichever is last. Data is latched on the rising edge of CE or WE, whichever is first. The byte write cycle can be CE controlled or WE controlled. Output Disable Returning OE or CE HIGH, whichever occurs first will terminate the read operation and place the l/O pins in the HIGH-Z state. Standby The device will enter standby mode when the CE signal is HIGH. The l/O pins are placed in the HIGH-Z, independent of the OE input state. Command Sequence The V29C51002T/V29C51002B does not provide the “reset” feature to return the chip to its normal state when an incomplete command sequence or an interruption has happened. In this case, normal operation (Read Mode) can be restored by issuing a “ non-existent ” c ommand sequence, for example Address: 5555H, Data FFH. Sector Erase Cycle T he V29C51002T/V29C51002B features a sector erase operation which allows each sector to be erased and reprogrammed without affecting data stored in other sectors. Sector erase operation is initiated by using a specific six-bus-cycle sequence: Two unlock program cycles, a setup command, two additional unlock program cycles, Table 1.

SA(5): Sector Address and the sector erase command (see Table 2). A sector must be first erased before it can be rewritten. While in the internal erase mode, the device ignores any program attempt into the device. The internal erase completion can be determined via DATA polling or toggle bit status. The V29C51002T/V29C51002B is shipped fully erased (all bits = 1). data, and the device is then ready for the next cycle. Toggle Bit (I/O6) T he V29C51002T/V29C51002B also features another method for determining the end of a program cycle. When the device is in the program cycle, any attempt to read the device will result in l/O6 toggling between 1 and 0. Once the program is completed, the toggling will stop. The device is then ready for the next operation. Examining the toggle bit may begin at any time during a program cycle. Chip Erase Cycle The V29C51002T/V29C51002B features a chiperase operation. The chip erase operation is initiated by using a specific six-bus-cycle sequence: two unlock program cycles, a setup command, two additional unlock program cycles, and the chip erase command (see Table 2). The automatic erase begins on the rising edge of the last WE or CE pulse in the command sequence and terminates when the data on DQ7 is “1”. Boot Block Protection Enabling/Disabling The V29C51002T/V29C51002B features hardware Boot Block Protection. The boot block sector protection is enabled when high voltage (12.5V) is applied to OE and A9 pins with CE pin LOW and WE pin LOW. The sector protection is disabled when high voltage is applied to OE, CE and A9 pins with WE pin LOW. Other pins can be HIGH or LOW. This is shown in table 1. Program Cycle Status Detection There are two methods for determining the state of the V29C51002T/V29C51002B during a program (erase/write) cycle: DATA Polling (I/O7) and Toggle Bit (I/O6). Autoselect Mode The V29C51002T/V29C51002B features an Autoselect mode to identify boot block locking status, device ID and manufacturer ID. Entering Autoselect mode is accomplished by applying a high voltage (VH) to the A9 Pin, or through a sequence of commands (as shown in table 2). Device will exit this mode once high voltage on A9 is removed or another command is loaded into the device. 10 DATA Polling (I/O7) The V29C51002T/V29C51002B features DATA polling to indicate the end of a program cycle. When the device is in the program cycle, any attempt to read the device will received the complement of the loaded data on I/O7. Once the program cycle is completed, I/O7 will show true V29C51002T/V29C51002B Rev. 2.1 October 2000 MOSEL VITELIC Boot Block Protection Status In Autoselect mode, performing a read at address location 3CXX2H (V29C51002T) or 0CXX2H (V29C51002B) will indicate boot block protection status. If the data is 01H, the boot block is protected. If the data is 00H, the boot block is unprotected. This is also shown is table 3. V29C51002T/V29C51002B Manufacturer ID I n Autoselect mode, performing a read at address XXXX0H will determine the manufacturer ID. 40H is the manufacturer code for Mosel Vitelic Flash. Hardware Data Protection VCC Detection: the program operation is inhibited when VCC is less than 3.5V. Noise Protection: a CE or WE pulse of less than 5ns will not initiate a program cycle. Program Inhibit: holding any one of OE LOW, CE HIGH or WE HIGH inhibits a program cycle. Device ID In Autoselect mode, performing a read at address XXX1H will determine whether the device is a Top Boot Block device or a Bottom Boot Block device. If the data is 02H, the device is a Top Boot Block. If the data is A2H, the device is a Bottom Boot Block device (see Table 3). Table 3.
