3 TMS2C BIT UV RSBL PROGRMMBL TMS2PC BIT PROGRMMBL RD-ONLY MMORY description (continued) These devices are fabricated using power-saving CMOS technology for high speed and simple interface with MOS and bipolar circuits. ll inputs (including program data inputs) can be driven by Series 4 TTL circuits without the use of external pull-up resistors. ach output can drive one Series 4 TTL circuit without external resistors. The data outputs are three-state for connecting multiple devices to a common bus. The TMS2C12 and the TMS2PC12 are pin compatible with 28-pin 12K MOS ROMs, PROMs, and PROMs. The TMS2C12 PROM is offered in a dual-in-line ceramic package (J suffix) designed for insertion in mounting hole rows on,2-mm (600-mil) centers. The TMS2PC12 OTP PROM is offered in a dual-in-line plastic package (N suffix) designed for insertion in mounting hole rows on,2-mm (600-mil) centers. The TMS2PC12 OTP PROM is also supplied in a 32-lead plastic leaded chip carrier package using 1,2-mm (0-mil) lead spacing (FM suffix), and in a 32-lead thin small-outline package (DD and DU suffixes). The TMS2C12 and TMS2PC12 are offered with two choices of temperature ranges of 0 C to 0 C (JL, NL, FML, and DDL suffixes) and 40 C to 8 C (J, N, FM, and DD suffixes). The TMS2C12 and TMS2PC12 are also offered with a 168-hour burn-in on both temperature ranges (JL4, NL4, FML4, DDL4, J4, N4, FM4, and DD4 suffixes); see table below. ll package styles conform to JDC standards.

One other 13-V supply is needed for programming. ll programming signals are TTL level. The device is programmed using the SNP! Pulse programming algorithm. The SNP! Pulse programming algorithm uses a V PP of 13 V and a V CC of 6. V for a nominal programming time of seven seconds. For programming outside the system, existing PROM programmers can be used. Locations can be programmed singly, in blocks, or at random. POST OFFIC BOX 1443 HOUSTON, TXS

The read mode requires a single -V supply. ll inputs are TTL level except for V PP during programming (13 V for SNP! Pulse) and 12 V on for signature mode.

VH = 12 V ± 0. V. 8 read/ output disable When the outputs of two or more TMS2C12s or TMS2PC12s 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. To read the output of a single device, a low-level signal is applied to the and G/V PP pins. ll 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 DQ. latchup immunity Latchup immunity on the TMS2C12 and TMS2PC12 is a minimum of 20 m 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 ctive I CC supply current can be reduced from 30 m to 00 µ (TTL-level inputs) or 20 µ (CMOS-level inputs) by applying a high TTL/CMOS signal to the pin. In this mode all outputs are in the high-impedance state. erasure ( TMS2C12) Before programming, the TMS2C12 PROM is erased by exposing the chip through the transparent lid to a high intensity ultraviolet light (wavelength 23 angstroms). PROM erasure before programming is necessary to assure that all bits are in the logic high state. Logic lows are programmed into the desired locations. programmed logic low can be erased only by ultraviolet light. The recommended minimum exposure dose (UV intensity exposure time) is -W s/cm 2. typical 12-mW/cm 2, filterless UV lamp erases the device in 21 minutes. The lamp should be located about 2. cm above the chip during erasure. It should be noted that normal ambient light contains the correct wavelength for erasure. Therefore, when using the TMS2C12, the window should be covered with an opaque label. 4 POST OFFIC BOX 1443 HOUSTON, TXS

5 TMS2C BIT UV RSBL PROGRMMBL TMS2PC BIT PROGRMMBL RD-ONLY MMORY initializing (TMS2PC12) The one-time programmable TMS2PC12 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. SNP! Pulse programming The 12K PROM and OTP PROM are programmed using the TI SNP! Pulse programming algorithm illustrated by the flowchart in Figure 1, which programs in a nominal time of seven seconds. ctual programming time varies as a function of the programmer used. The SNP! 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/V PP = 13 V, V CC = 6. V, and =V IL. Data is presented in parallel (eight bits) on pins DQ0 to DQ. Once addresses and data are stable, 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 SNP! Pulse programming routine is complete, all bits are verified with V CC = V, G/V PP = V IL, and = V IL. program inhibit Programming can be inhibited by maintaining a high level input on the pin. program verify Programmed bits can be verified when G/V PP and = V IL. signature mode The signature mode provides access to a binary code identifying the manufacturer and type. This mode is activated when is forced to 12 V ± 0. V. Two identifier bytes are accessed by 0; i.e., 0 = V IL accesses the manufacturer code, which is output on DQ0 DQ; 0 = V IH accesses the device code, which is output on DQ0 DQ. ll other addresses must be held at V IL. The manufacturer code for these devices is, and the device code is 8. POST OFFIC BOX 1443 HOUSTON, TXS
