Y-DECODER X-DECODER OUTPUT BUFFERS . . . . . . . . Programming of multiple MX27C1000As in parallel with different data is also easily accomplished by using the Program Inhibit Mode. Except for CE and OE, all like inputs of the parallel MX27C1000A may be common. A TTL low-level program pulse applied to an MX27C1000A CE input with VPP = 12.5 ± 0.5 V and PGM LOW will program that MX27C1000A. A high-level CE input inhibits the other MX27C1000As from being programmed. Q0~Q17 Y-SELECT 1M BIT CELL MAXTRIX PROGRAM VERIFY MODE VPP FUNCTIONAL 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. DESCRIPTION THE PROGRAMMING OF THE MX27C1000A AUTO IDENTIFY MODE When the MX27C1000A 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. 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 MX27C1000A. For programming, the data to be programmed is applied with 8 bits in parallel to the data pins. Vcc must be applied simultaneously or before Vpp, and removed simultaneously or after Vpp. When programming an MXIC OTP ROM, a 01.uF capacitor is required across Vpp and ground to suppress spurious voltage transients which may damage the device. 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. 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 10us 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%. P/N: PM0733 Byte 0 ( A0 = VIL) represents the manufacturer code, and byte 1 (A0 = VIH), the device identifier code. For the MX27C1000A, these two identifier bytes are given in the Mode Select Table. All identifiers for manufacturer and device codes will possess odd parity, with the MSB (DQ7) defined as the parity bit. READ MODE The MX27C1000A has two control functions, both of which must be logically satisfied in order to obtain data at the outputs. Chip Enable (CE) is the power control and should be used for device selection. Output Enable REV. 1.3, AUG. 27, 2003 2 MX27C1000A It is recommended that CE be decoded and used as the primary device-selecting function, while OE be made a common connection to all devices in the array and connected to the READ line from the system control bus. This assures that all deselected memory devices are in their low-power standby mode and that the output pins are only active when data is desired from a particular memory device. (OE) is the output control and should be used to gate data to the output pins, independent of device selection. Assuming that addresses are stable, address access time (tACC) is equal to the delay from CE to output (tCE). Data is available at the outputs tQE after the falling edge of OE, assuming that CE has been LOW and addresses have been stable for at least tACC - tQE. STANDBY MODE SYSTEM CONSIDERATIONS The MX27C1000A has a CMOS standby mode which reduces the maximum VCC current to 100 uA. It is placed in CMOS standby when CE is at VCC ± 0.3 V. The MX27C1000A also has a TTL-standby mode which reduces the maximum VCC current to 1.5 mA. It is placed in TTL-standby when CE is at VIH. When in standby mode, the outputs are in a high-impedance state, independent of the OE input. During the switch between active and standby conditions, transient current peaks are produced on the rising and falling edges of Chip Enable. The magnitude of these transient current peaks is dependent on the output capacitance loading of the device. At a minimum, a 0.1 uF ceramic capacitor (high frequency, low inherent inductance) should be used on each device between VCC and GND to minimize transient effects. In addition, to overcome the voltage drop caused by the inductive effects of the printed circuit board traces on EPROM arrays, a 4.7 uF bulk electrolytic capacitor should be used between VCC and GND for each eight devices. The location of the capacitor should be close to where the power supply is connected to the array. TWO-LINE OUTPUT CONTROL FUNCTION To accommodate multiple memory connections, a twoline control function is provided to allow for: 1. Low memory power dissipation, 2. Assurance that output bus contention will not occur.
