8 / 22 page Device operation M27C512 8/22 2.7 Program Inhibit Programming of multiple M27C512s in parallel with different data is also easily accomplished. Except for E, all like inputs including GVPP of the parallel M27C512 may be common. A TTL low level pulse applied to a M27C512's E input, with VPP at 12.75V, will program that M27C512. A high level E input inhibits the other M27C512s 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 G at VIL. Data should be verified with tELQV after the falling edge of E. 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 and 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 25°C ± 5°C ambient temperature range that is required when programming the M27C512. To activate the ES mode, the programming equipment must force 11.5V to 12.5V on address line A9 of the M27C512. Two identifier bytes may then be sequenced from the device outputs by toggling address line A0 from VIL to VIH. All other address lines must be held at VIL during Electronic Signature mode. Byte 0 (A0 = VIL) represents the manufacturer code and byte 1 (A0 = VIH) the device identifier code. For the STMicroelectronics M27C512, these two identifier bytes are given in <Blue>Table 4. and can be read-out on outputs Q7 to Q0. |
