OVERVIEW
The S93VP662 and S93VP663 are 4K-bit serial E2PROM memories integrated with a precision V
CC
sense circuit. The sense circuit will disable write opera­tions whenever VCC falls below the V
LOCK
voltage. They are fabricated using SUMMIT’s advanced CMOS E2PROM technology and is suitable for both 3 and 5 volt systems.
Both devices have 4k-bits of E2PROM memory that is accessible via the industry standard microwire bus. The S93VP662 is configured with an internal ORG pin tied low providing an 8-bit byte organization and the S93VP663 is configured with an internal ORG pin tied high providing a 16-bit word organization. Both the S93VP662 and S93VP663 have page write capability. The devices are designed for a minimum 1,000,000 program/erase cycles and have data retention in ex­cess of 100 years.

DEVICE OPERATION
APPLICATIONS
The S93VP662/VP663 was designed specifically for applications where the integrity of the stored data is paramount. In recent years, as the operating voltage range of serial E2PROMs has widened, most semicon­ductor manufacturers have arbitrarily eliminated their V
CC
sense circuits. The S93VP662/VP663 will protect your data by guaranteeing write lockout below the se­lected VCC Lockout voltage.
VCC Lockout
The S93VP662/VP663 has an on-board precision V
CC
sense circuit. Whenever VCC is below V
LOCK
, the S93VP662/VP663 will disable the internal write circuitry. The VCC lockout circuit will ensure a higher level of data integrity than can be expected from industry standard devices that have either a very loose specification or no VCC lockout specification.
During a power-on sequence all writes will be inhibited below the V
LOCK
level and will continue to be held in a
write inhibit state for approximately 200ms after V
CC
reaches, then stays at or above V
LOCK
. The 200ms delay provides a buffer space for the microcontroller to com­plete its power-on initialization routines (reading is OK) while still protecting against inadvertent writes.
During a power-down sequence initiation of writes will be inhibited whenever VCC falls below V
LOCK
. This will guard against the system’s microcontroller performing an inadvertent write within the ‘danger zone’. (see AN003)
GENERAL OPERATION
The S93VP662/VP663 is a 4096-bit nonvolatile memory intended for use with industry standard microproces­sors. The S93VP663 is organized as X16, seven 11-bit instructions control the reading, writing and erase operations of the device. The S93VP662 is organized as X8, seven 12-bit instructions control the reading, writing and erase operations of the device. The device operates on a single 3V or 5V supply and will generate on chip, the high voltage required during any write operation.
Instructions, addresses, and write data are clocked into the DI pin on the rising edge of the clock (SK). The DO pin is normally in a high impedance state except when reading data from the device, or when checking the ready/busy status after a write operation.
The ready/busy status can be determined after the start of a write operation by selecting the device (CS high) and polling the DO pin; DO low indicates that the write operation is not completed, while DO high indicates that the device is ready for the next instruction. If necessary, the DO pin may be placed back into a high impedance

state during chip select by shifting a dummy “1” into the DI pin. The DO pin will enter the high impedance state on the falling edge of the clock (SK). Placing the DO pin into the high impedance state is recommended in appli­cations where the DI pin and the DO pin are to be tied together to form a common DI/O pin.
The format for all instructions is: one start bit; two op code bits and either eight (x16) or nine (x8) address/ instruction bits.
Read
Upon receiving a READ command and an address (clocked into the DI pin), the DO pin of the S93VP662/ VP663 will come out of the high impedance state and, will first output an initial dummy zero bit, then begin shifting out the data addressed (MSB first). The output data bits will toggle on the rising edge of the SK clock and are stable after the specified time delay (t
PD0
or
t
PD1
).
Write
After receiving a WRITE command, address and the data, the CS (Chip Select) pin must be deselected for a minimum of 250ns (t
CSMIN
). The falling edge of CS will start automatic erase and write cycle to the memory location specified in the instruction. The ready/busy status of the S93VP662/VP663 can be determined by selecting the device and polling the DO pin.
Erase
Upon receiving an ERASE command and address, the CS (Chip Select) pin must be deslected for a minimum of 250ns (t
CSMIN
). The falling edge of CS will start the auto erase cycle of the selected memory location. The ready/busy status of the S93VP662/VP663 can be determined by selecting the device and polling the DO pin. Once cleared, the content of a cleared location returns to a logical “1” state.

Erase/Write Enable and Disable
The S93VP662/VP663 powers up in the write disable state. Any writing after power-up or after an EWDS (write disable) instruction must first be preceded by the EWEN (write enable) instruction. Once the write in­struction is enabled, it will remain enabled until power to the device is removed, or the EWDS instruction is sent. The EWDS instruction can be used to disable all S93VP662/VP663 write and clear instructions, and will prevent any accidental writing or clearing of the device. Data can be read normally from the device regardless of the write enable/disable status.
Erase All
Upon receiving an ERAL command, the CS (Chip Select) pin must be deselected for a minimum of 250ns (t
CSMIN
). The falling edge of CS will start the self clocking
clear cycle of all memory locations in the device. The
clocking of the SK pin is not necessary after the device has entered the self clocking mode. The ready/busy status of the S93VP662/VP663 can be determined by selecting the device and polling the DO pin. Once cleared, the contents of all memory bits return to a logical “1” state.
Write All
Upon receiving a WRAL command and data, the CS (Chip Select) pin must be deselected for a minimum of 250ns (t
CSMIN
). The falling edge of CS will start the self clocking data write to all memory locations in the device. The clocking of the SK pin is not necessary after the device has entered the self clocking mode. The ready/ busy status of the S93VP662/VP663 can be determined by selecting the device and polling the DO pin. It is not necessary for all memory locations to be cleared before the WRAL command is executed.
