MX27C1000 1M-BIT [128K x 8] CMOS EPROM FEATURES • • • • • • 128K x 8 organization Single +5V power supply +12.5V programming voltage Fast access time: 45/55/70/90/100/120/150 ns Totally static operation Completely TTL compatible • Operating current: 30mA • Standby current: 100uA • Package type: 32 pin plastic DIP 32 pin SOP 32 pin PLCC 32 pin TSOP GENERAL DESCRIPTION The MX27C1000 is a 5V only, 1M-bit, One Time Programmable Read Only Memory. It is organized as 128K words by 8 bits per word, operates from a single + 5 volt supply, has a static standby mode, and features fast single address location programming. All programming signals are TTL levels, requiring a single pulse. For programming outside from the system, existing EPROM programmers may be used. The MX27C1000 supports an intelligent fast programming algorithm which can result in programming time of less than thirty seconds. This EPROM is packaged in industry standard 32 pin dual-in-line packages, 32 lead PLCC , 32 lead SOP , and 32 lead TSOP packages.

Except for CE and OE, all like inputs of the parallel MX27C1000 may be common. A TTL low-level program pulse applied to an MX27C1000 CE input with VPP = 12.5 ± 0.5 V and PGM LOW will program that MX27C1000. A high-level CE input inhibits the other MX27C1000s from being programmed. THE PROGRAMMING OF THE MX27C1000 When the MX27C1000 is delivered, or it is erased, the chip has all 1M bits in the "ONE" or HIGH state. "ZEROs" are loaded into the MX27C1000 through the procedure of programming. For programming, the data to be programmed is applied with 8 bits in parallel to the data pins. www.DataSheet4U.com Vcc must be applied simultaneously or before Vpp, and removed simultaneously or after Vpp. When programming an MXIC EPROM, a 01.uF capacitor is required across Vpp and ground to suppress spurious voltage transients which may damage the device. PROGRAM VERIFY MODE Verification should be performed on the programmed bits to determine that they were correctly programmed. The verification should be performed with OE and CE at VIL, PGM at VIH, and VPP at its programming voltage. FAST PROGRAMMING The device is set up in the fast programming mode when the programming voltage VPP = 12.75V is applied, with VCC = 6.25 V and PGM = VIL(or OE = VIH) (Algorithm is shown in Figure 1). The programming is achieved by applying a single TTL low level 100us pulse to the PGM input after addresses and data line are stable. If the data is not verified, an additional pulse is applied for a maximum of 25 pulses. This process is repeated while sequencing through each address of the device. When the programming mode is completed, the data in all address is verified at VCC = VPP = 5V ± 10%. AUTO IDENTIFY MODE The auto identify mode allows the reading out of a binary code from an EPROM that will identify its manufacturer and device type. This mode is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. This mode is functional in the 25°C ± 5° C ambient temperature range that is required when programming the MX27C1000. P/N: PM0234 REV. 5.9, NOV. 19, 2002 2 MX27C1000 To activate this mode, the programming equipment must force 12.0 ± 0.5 V on address line A9 of the device. 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 auto identify mode. Byte 0 ( A0 = VIL) represents the manufacturer code, and byte 1 (A0 = VIH), the device identifier code. For the MX27C1000, these two identifier bytes are given in the Mode Select Table. All identifi.
