It is organized as 512K x 8 or 256K x 16, 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 MX27C4111 supports a intelligent fast programming algorithm which can result in programming time of less than two minutes. MX27C4111 provides Page Read Access Mode which can greatly reduce the read access time. Normal read access time and Page Mode read access time is as fast as 90/50ns. It is designed to be compatible with all microprocessors and similar applications in which high perofmrance, large bit storage and simple interfacing are important design considerations.

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 MX27C4111. When the MX27C4111 is delivered, or it is erased, the chip has all 4M bits in the "ONE" or HIGH state. "ZEROs" are loaded into the MX27C4111 through the procedure of programming. For programming, the data to be programmed is applied with 16 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 EPROM, a 0.1uF 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 Byte 0 ( A0 = VIL) represents the manufacturer code, and byte 1 (A0 = VIH), the device identifier code. For the MX27C4111, 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 (Q15) defined as the parity bit. 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 OE = VIH (Algorithm is shown in Figure 1). The programming is achieved by applying a single TTL low level 100us pulse to the CE 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%. READ MODE The MX27C4111 provides page mode with 8 words/16 bytes per page. In order to get the benefit of fast page read, the user should keep chip enable(CE) low and toggle address A0~A2 in word mode or A-1~A2 in byte mode. Page Read access time(tPA) is equal to the delay from address stable to data output. It is twice as fast as normal tACC and is highly recommended. PROGRAM INHIBIT MODE Programming of multiple MX27C4111's 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 MX27C4111 may be common. A TTL low-level program pulse applied to an MX27C4111 CE input with VPP = 12.5 ± 0.5 V will program the MX27C4111. A high-level CE input inhibits the other MX27C4111s from being programmed. WORD-WIDE MODE With BYTE/VPP at VCC ± 0.2V outputs Q0-7 present data Q0-7 and outputs Q8-15 present data Q8-15, after CE and OE are appropriately enabled. BYTE-WIDE MODE PROGRAM VERIFY MODE With BYTE/VPP at GND ± 0.2V, outputs Q8-15 are tristated. If Q15/A-1 = VIH, outputs Q0-7 present data bits Q8-15. If Q15/A-1 = VIL, outputs Q0-7 present data bits Q0-7. Verification should be performed on the programmed bits to determine that they were correctly programmed. The verification should be performed with OE at VIL, CE at VIH, and VPP at its programming voltage. P/N: PM0239 3 REV. 2.7, NOV. 19, 2002 MX27C4111 STANDBY MODE 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. The MX27C4111 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 MX27C4111 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. SYSTEM CONSIDERATIONS 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. 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 MODE SELECT TABLE BYTE/ MODE CE OE A9 A0 Q15/A-1 VPP(5) Q8-14 Q0-7 Read (Word) VIL VIL X X Q15 Out VCC Q8-14 Out Q0-7 Out Read (Upper Byte) VIL VIL X X VIH GND High Z Q8-15 Out Read (Lower Byte) VIL VIL X X VIL GND High Z Q0-7 Out Output Disable VIL VIH X X High Z X High Z High Z Standby VIH X X X High Z X High Z High Z Program VIL VIH X X Q15 In VPP Q8-14 In Q0-7 In Program Verify VIH VIL X X Q5 Out VPP Q8-14 Out Q0-7 Out Program Inhibit VIH VIH X X High Z VPP High Z High Z Manufacturer Code(3) VIL VIL VH VIL 0B VCC 00H C2H Device Code(3) VIL VIL VH VIH 1B VCC 38H 00H NOTES: 1.VH = 12.0V ± 0.5V 2.X = Either VIH or VIL 3.A1 - A8, A10 - A17 = VIL (For auto select) 4.See DC Programming Characteristics for VPP voltages. 5.BYTE/VPP is intended for operation under DC Voltage conditions only. 6.Manufacture code = 00C2H Device code = B800H P/N: PM0239 4 REV. 2.7, NOV. 19, 2002 MX27C4111 FIGURE 1.
