device description m27v160 8/26 2 device description ta bl e 2 lists the operating modes of the m27v160. a single power supply is required in the read mode. all inputs are ttl compatible except for v pp and 12v on a9 for the electronic signature. 2.1 read mode the m27v160 has two organisations, word-wide and byte-wide. the organisation is selected by the signal level on the byte v pp pin. when byte v pp is at v ih the word-wide organisation is selected and the q15a?1 pin is used for q15 data output. when the byte v pp pin is at v il the byte-wide organisation is selected and the q15a?1 pin is used for the address input a?1. when the memory is logically regarded as 16 bit wide, but read in the byte-wide organisation, then with a?1 at v il the lower 8 bits of the 16 bit data are selected and with a?1 at v ih the upper 8 bits of the 16 bit data are selected. the m27v160 has two control functions, both of which must be logically active in order to obtain data at the outputs. in addition the word-wide or byte- wide organisation must be selected. chip enable (e ) is the power control and should be used for device selection. output enable (g ) is the output control and should be used to gate data to the output pins independent of device selection. assuming that the addresses are stable, the address access time (t avqv ) is equal to the delay from e to output (t elqv ). data is available at the output after a delay of t glqv from the falling edge of g , assuming that e has been low and the addresses have been stable for at least t avqv -t glqv . 2.2 standby mode the m27v160 has a standby mode which reduces the active current from 20ma to 20a with low voltage operation v cc 3.6v, see read mode dc characteristics table for details.the m27v160 is placed in the standby mode by applying a cmos high signal to the table 2. operating modes (1) 1. x = v ih or v il , v id = 12v 0.5v. mode e g byte v pp a9 q15a?1 q14-q8 q7-q0 read word-wide v il v il v ih x data out data out data out read byte-wide upper v il v il v il xv ih hi-z data out read byte-wide lower v il v il v il xv il hi-z data out output disable v il v ih x x hi-z hi-z hi-z program v il pulse v ih v pp x data in data in data in verify v ih v il v pp x data out data out data out program inhibit v ih v ih v pp x hi-z hi-z hi-z standby v ih x x x hi-z hi-z hi-z electronic signature v il v il v ih v id code codes codes obsolete product(s) - obsolete product(s)
m27v160 device description 9/26 e input. when in the standby mode, the outputs are in a high impedance state, independent of the g input. 2.3 two-line output control because eproms are usually used in larger me mory arrays, this product features a 2 line control function which accommodates the use of multiple memory connection. the two line control function allows: the lowest possible memory power dissipation, complete assurance that output bus contention will not occur. for the most efficient use of these two control lines, e should be decoded and used as the primary device selecting function, while g should be made a common connection to all devices in the array and connected to the read line from the system control bus. this ensures that all deselected memory devices are in their low power standby mode and that the output pins are only active when data is required from a particular memory device. 2.4 system considerations the power switching characteristics of advanced cmos eproms require careful decoupling of the supplies to the devices. the supply current i cc has three segments of importance to the system designer: the standby current, the active current and the transient peaks that are produced by the falling and rising edges of e . the magnitude of the transient current peaks is dependent on the capacitive and inductive loading of the device outputs. the associated transient voltage peaks can be suppressed by complying with the two line output control and by properly selected decoupling capacitors. it is recommended that a 0.1f ceramic capacitor is used on every device between v cc and v ss . this should be a high frequency type of low inherent inductance and should be placed as close as possible to the device. in addition, a 4.7f electrolytic capacitor should be used between v cc and v ss for every eight devices. this capacitor should be mounted near the power supply connection point. the purpose of this capacitor is to overcome the voltage drop caused by the inductive effects of pcb traces. 2.5 programming the m27v160 has been designed to be fully compatible with the m27c160. as a result the m27v160 can be programmed as the m27c160 on the same programming equipments applying 12.75v on v pp and 6.25v on v cc by the use of the same presto iii algorithm. when delivered (and after each erasure for uv eprom), all bits of the m27v160 are in the '1' state. data is introduced by selectively programming '0's to the desired bit locations. although only '0's will be programmed, both '1 's and '0's can be present in the data word. the only way to change a '0' to a '1' is by die exposure to ultraviolet light (uv eprom). the m27v160 is in the programming mode when v pp input is at 12.5v, g is at v ih and e is pulsed to v il . the data to be programmed is applied to 16 bits in parallel to the data output pins. the levels required for the address and data inputs are ttl. v cc is specified to be 6.25v 0.25v. obsolete product(s) - obsolete product(s)
device description m27v160 10/26 2.6 presto iii prog ramming algorithm the presto iii programming algorithm allows the whole array to be programed with a guaranteed margin in a typical time of 52.5 seconds. programming with presto iii consists of applying a sequence of 50s program pulses to each word until a correct verify occurs (see figure 5. ). during programing and verify operation a margin mode circuit is automatically activated to guarantee that each cell is programed with enough margin. no overprogram pulse is applied since the verify in margin mode at v cc much higher than 3.6v provides the necessary margin to each programmed cell. figure 5. programming flowchart 2.7 program inhibit programming of multiple m2 7v160s in parallel with different data is also easily accomplished. except for e , all like inputs including g of the parallel m27v160 may be common. a ttl low level pulse applied to a m27v160's e input and v pp at 12.5v, will program that m27v160. a high level e input inhibits the other m27v160s from being programmed. 2.8 program verify a verify (read) should be performed on the programmed bits to determine that they were correctly programmed. the verify is accomplished with e at v ih and g at v il , v pp at 12.5v and v cc at 6.25v. ai00901b n = 0 last addr verify e = 50 s pulse ++n = 25 ++ addr v cc = 6.25v, v pp = 12.5v fail check all words bytev pp =v ih 1st: v cc = 5v 2nd: v cc = 3v yes no yes no yes no obsolete product(s) - obsolete product(s)
m27v160 device description 11/26 2.9 electronic signature the electronic signature (es) mode allows the reading out of a binary code from an eprom that will identify its manufacturer an d type. this mode is intended for use by programming equipment to automatically match the device to be programmed with its corresponding programming algorithm. the es mode is functional in the 25c 5c ambient temperature range that is required when programming the m27v160. to activate the es mode, the programming equipment must force 11.5v to 12.5v on address line a9 of the m27v160, with v pp = v cc = 5v. two identifier bytes may then be sequenced from the device outputs by toggling address line a0 from v il to v ih . all other address lines must be held at v il during electronic signature mode. byte 0 (a0 = v il ) represents the manufacturer code and byte 1 (a0 = v ih ) the device identifier code. for the stmicroelectronics m27v160, these two identifier bytes are given in ta bl e 3 and can be read-out on outputs q7 to q0. note that the m27v160 and m27c160 have the same identifier bytes. 2.10 erasure operation (applies to uv eprom) the erasure characteristics of the m27v160 is such that erasure begins when the cells are exposed to light with wavelengths shorter than approximately 4000 ?. it should be noted that sunlight and some type of fluorescent lamps have wavelengths in the 3000-4000 ? range. research shows that constant exposure to room level fluorescent lighting could erase a typical m27v160 in about 3 years, while it would take approximately 1 week to cause erasure when exposed to direct sunlight. if the m27v160 is to be exposed to these types of lighting conditions for extended periods of time, it is suggested that opaque labels be put over the m27v160 window to prevent unintentional erasure. the recommended erasure procedure for m27v160 is exposure to short wave ultraviolet light which has a wavelength of 2537 ?. the integrated dose (i.e. uv intensity x exposure time) for erasure should be a minimum of 30 w-sec/cm 2 . the erasure time with this dosage is approximately 30 to 40 minutes using an ultraviolet lamp with 12000 w/cm 2 power rating. the m27v160 should be placed within 2.5 cm (1 inch) of the lamp tubes during the erasure. some lamps have a filter on their tubes which should be removed before erasure. table 3. electronic signature identifier a0 q15 and q7 q14 and q6 q13 and q5 q12 and q4 q11 and q3 q10 and q2 q9 and q1 q8 and q0 hex data manufacturer?s code v il 00100000 20h device code v ih 10110001 b1h obsolete product(s) - obsolete product(s)
