sony ? cxk77p36e160gb / cxk77p18e160gb preliminary 16mb lw r-l and 8mb lw r-l w/ ec, rev 1.1 5 / 25 march 2, 2001 ? clock truth table ? dynamic m2 mode pin state changes although m2 is defined as a static input (that is, it must be tied ?high? or ?low? at power-up), in some instance (such as during device testing) it may be desirable to change its state dynamically (that is, without first powering off the sram) while preserving the contents of the memory array. if so, the following criteria must be met: 1. at least two (2) consecutive deselect operations must be initiated prior to changing the state of m2, to ensure that the most recent read or write operation completes successfully. 2. at least thirty-two (32) consecutive deselect operations must be initiated after changing the state of m2 before any read or write operations can be initiated, to allow the sram sufficient time to recognize the change in state. ? sleep (power down) mode sleep (power down) mode is provided through the asynchronous input signal zz. when zz is asserted (high), the output drivers will go to a hi-z state, and the sram will begin to draw standby current. contents of the memory array will be preserved. an enable time (t zze ) must be met before the sram is guaranteed to be in sleep mode, and a recovery time (t zzr ) must be met before the sram can resume normal operation. ? programmable impedance output drivers these devices have programmable impedance output drivers. the output impedance is controlled by an external resistor, rq, connected between the sram?s zq pin and v ss , and is equal to one-fifth the value of this resistor, nominally. see the dc electrical characteristics section for further information. the output impedance is updated whenever the output drivers are in a hi-z state. consequently, impedance updates will occur during write and deselect operations. at power up, 8192 clock cycles followed by an impedance update via one of the three methods described above are required to ensure that the output impedance has reached the desired value. after power up, periodic impedance updates via write or deselect operations are also required to ensure that the output imped- ance remains within specified tolerances. ? power-up sequence for reliability purposes, sony recommends that power supplies power up in the following sequence: v ss , v dd , v ddq , v ref , and inputs. v ddq should never exceed v dd . if this power supply sequence cannot be met, a large bypass diode may be required between v dd and v ddq . please contact sony memory application department for further information. k zz ss (t n ) sw (t n ) sbw x (t n ) operation dq (t n ) dq (t n+1 ) x h x x x sleep (power down) mode hi - z hi - z l ? h l h x x deselect hi - z x l ? h l l h x read q(t n ) x l ? h l l l l write all bytes hi - z d(t n ) l ? h l l l x write bytes with sbw x = l hi - z d(t n ) l ? h l l l h abort write hi - z x

(inserted between tdi and tdo) when the appropriate sequence of commands is given to the tap controller. instruction register (3 bits) the instruction register stores the instructions that are executed by the tap controller when the tap controller is in the ?run-test / idle? state, or in any of the various ?data register? states. it is loaded with the idcode instruction at power- up, or when the tap controller is in the ?test-logic reset? state or the ?capture-ir? state. it is inserted between tdi and tdo when the tap controller is in the ?shift-ir? state, at which time it can be loaded with a new instruction. how- ever, newly loaded instructions are not executed by the tap controller until the tap controller has reached the ?update- ir? state. the instruction register is 3 bits wide, and is encoded as follows: bit 0 is the lsb of the instruction register, and bit 2 is the msb. when the instruction register is selected, tdi serially shifts data into the msb, and the lsb serially shifts data out through tdo. id register (32 bits) the id register is loaded with a predetermined device- and manufacturer-specific identification code when the idcode instruction has been loaded into the instruction register and the tap controller is in the ?capture-dr? state. it is inserted between tdi and tdo when the idcode instruction has been loaded into the instruction register and the tap control- ler is in the ?shift-dr? state. the id register is 32 bits wide, and is encoded as follows: bit 0 is the lsb of the id register, and bit 31 is the msb. when the id register is selected, tdi serially shifts data into the msb, and the lsb serially shifts data out through tdo. code (2:0) instruction description 000 bypass inserts the bypass register between tdi and tdo. 001 idcode inserts the id register between tdi and tdo. 010 sample-z captures the sram?s i/o ring contents in the boundary scan register. inserts the boundary scan register between tdi and tdo. disables the sram?s data out- put drivers. 011 bypass inserts the bypass register between tdi and tdo. 100 sample captures the sram?s i/o ring contents in the boundary scan register. inserts the boundary scan register between tdi and tdo. 101 private do not use. reserved for manufacturer use only. 110 bypass inserts the bypass register between tdi and tdo. 111 bypass inserts the bypass register between tdi and tdo. device revision number (31:28) part number (27:12) sony id (11:1) start bit (0) 512k x 36 xxxx 0000 0000 0100 1010 0000 1110 001 1 1m x 18 xxxx 0000 0000 0100 1011 0000 1110 001 1
