description (continued)
These devices are fabricated using power-saving CMOS technology for high speed and simple interface with MOS and bipolar circuits. All inputs (including program data inputs) can be driven by Series 74 TTL circuits without the use of external pullup resistors. Each output can drive one Series 74 TTL circuit without external resistors.
The data outputs are 3-state for connecting multiple devices to a common bus. The TMS27C512 and the TMS27PC512 are pin compatible with 28-pin 512K MOS ROMs, PROMs, and EPROMs.
The TMS27C512 EPROM is offered in a dual-in-line ceramic package (J suffix) designed for insertion in mounting hole rows on 15,2-mm (600-mil) centers. The TMS27PC512 OTP PROM is supplied in a 32-lead plastic leaded chip carrier package using 1,25-mm (50-mil) lead spacing (FM suffix).
The TMS27C512 and TMS27PC512 are offered with two choices of temperature ranges of 0°C to 70°C (JL and FML suffix) and – 40°C to 85°C (JE and FME suffix). See Table 1.
All package styles conform to JEDEC standards.

These EPROMs and OTP PROMs operate from a single 5-V supply (in the read mode), thus are ideal for use in microprocessor-based systems. One other 13-V supply is needed for programming. All programming signals are TTL level. The device is programmed using the SNAP! Pulse programming algorithm. The SNAP! Pulse programming algorithm uses a V
of 13 V and a VCC of 6.5 V for a nominal programming time of seven seconds.

For programming outside the system, existing EPROM programmers can be used. Locations can be programmed singly, in blocks, or at random.

read/output disable
When the outputs of two or more TMS27C512s or TMS27PC512s are connected in parallel on the same bus, the output of any particular device in the circuit can be read with no interference from the competing outputs of the other devices. T o read the output of a single device, a low-level signal is applied to the E
and G/VPP pins. All other devices in the circuit should have their outputs disabled by applying a high-level signal to one of these pins. Output data is accessed at pins DQ0 through DQ7.
latchup immunity
Latchup immunity on the TMS27C512 and TMS27PC512 is a minimum of 250 mA on all inputs and outputs. This feature provides latchup immunity beyond any potential transients at the P .C. board level when the devices are interfaced to industry-standard TTL or MOS logic devices. Input-output layout approach controls latchup without compromising performance or packing density.
power down
Active I inputs) by applying a high TTL/CMOS signal to the E
supply current can be reduced from 30 mA to 500 µA (TTL-level inputs) or 250 µA (CMOS-level
CC
pin. In this mode all outputs are in the high-impedance
state.
erasure (TMS27C512)
Before programming, the TMS27C512 EPROM is erased by exposing the chip through the transparent lid to a high intensity ultraviolet light (wavelength 2537 angstroms). EPROM erasure before programming is necessary to assure that all bits are in the logic high state. Logic lows are programmed into the desired locations. A programmed logic low can be erased only by ultraviolet light. The recommended minimum exposure dose (UV intensity × exposure time) is 15-Ws/cm
2
. A typical 12-mW/cm2, filterless UV lamp erases the device in 21 minutes. The lamp should be located about 2.5 cm above the chip during erasure. It should be noted that normal ambient light contains the correct wavelength for erasure. Therefore, when using the TMS27C512, the window should be covered with an opaque label.

initializing (TMS27PC512)
The one-time programmable TMS27PC512 PROM is provided with all bits in the logic high state, then logic lows are programmed into the desired locations. Logic lows programmed into a PROM cannot be erased.
SNAP! Pulse programming
The 512K EPROM and OTP PROM are programmed using the TI SNAP! Pulse programming algorithm illustrated by the flowchart in Figure 1, which programs in a nominal time of seven seconds. Actual programming time varies as a function of the programmer used.
The SNAP! Pulse programming algorithm uses initial pulses of 100 microseconds (µs) followed by a byte verification to determine when the addressed byte has been successfully programmed. Up to 10 (ten) 100-µs pulses per byte are provided before a failure is recognized.
The programming mode is achieved with G (eight bits) on pins DQ0 to DQ7. Once addresses and data are stable, E
/VPP= 13 V , VCC= 6.5 V , and E =VIL. Data is presented in parallel
is pulsed.
More than one device can be programmed when the devices are connected in parallel. Locations can be programmed in any order. When the SNAP! Pulse programming routine is complete, all bits are verified with V
= 5 V, G/VPP = V
CC
and E = VIL.

Programming can be inhibited by maintaining a high level input on the E

signature mode
The signature mode provides access to a binary code identifying the manufacturer and type. This mode is activated when A9 is forced to 12 V . T wo identifier bytes are accessed by toggling A0. All other addresses must be held low. the signature code for these devices is 9785. A0 selects the manufacturer’s code 97 (Hex), and A0 high selects the device code 85, as shown in Table 3.
