Of the ten available OLMCs, two OLMCs have access to eight product terms (pins 17 and 27), two have ten product terms (pins 18 and 26), two have twelve product terms (pins 19 and 25), two have fourteen product terms (pins 20 and 24), and two OLMCs have sixteen product terms (pins 21 and 23). In addition to the product terms available for logic, each OLMC has an additional product-term dedicated to output enable control. The ispGAL22V10 has a product term for Asynchronous Reset (AR) and a product term for Synchronous Preset (SP). These two product terms are common to all registered OLMCs. The Asynchronous Reset sets all registers to zero any time this dedicated product term is asserted. The Synchronous Preset sets all registers to a logic one on the rising edge of the next clock pulse after this product term is asserted. The output polarity of each OLMC can be individually programmed to be true or inverting, in either combinatorial or registered mode. This allows each output to be individually configured as either active high or active low. NOTE: The AR and SP product terms will force the Q output of the flip-flop into the same state regardless of the polarity of the output. Therefore, a reset operation, which sets the register output to a zero, may result in either a high or low at the output pin, depending on the pin polarity chosen. A R D 4 TO 1 MUX Q CLK Q SP 2 TO 1 MUX ispGAL22V10 OUTPUT LOGIC MACROCELL (OLMC) OUTPUT LOGIC MACROCELL CONFIGURATIONS Each of the Macrocells of the ispGAL22V10 has two primary functional modes: registered, and combinatorial I/O. The modes and the output polarity are set by two bits (SO and S1), which are normally controlled by the logic compiler. Each of these two primary modes, and the bit settings required to enable them, are described below and on the following page. NOTE: In registered mode, the feedback is from the /Q output of the register, and not from the pin; therefore, a pin defined as registered is an output only, and cannot be used for dynamic I/O, as can the combinatorial pins. COMBINATORIAL I/O In combinatorial mode the pin associated with an individual OLMC is driven by the output of the sum term gate. Logic polarity of the output signal at the pin may be selected by specifying that the output buffer drive either true (active high) or inverted (active low). Output tri-state control is available as an individual product-term for each output, and may be individually set by the compiler as either “on” (dedicated output), “off” (dedicated input), or “productterm driven” (dynamic I/O). Feedback into the AND array is from the pin side of the output enable buffer. Both polarities (true and inverted) of the pin are fed back into the AND array. REGISTERED In registered mode the output pin associated with an individual OLMC is driven by the Q output of that OLMC’s D-type flip-flop. Logic polarity of the output signal at the pin may be selected by specifying that the output buffer drive either true (active high) or inverted (active low). Output tri-state control is available as an individual product-term for each OLMC, and can therefore be defined by a logic equation. The D flip-flop’s /Q output is fed back into the AND array, with both the true and complement of the feedback available as inputs to the AND array. 3 Specifications ispGAL22V10 REGISTERED MODE AR AR Q D CLK Q D Q CLK SP Q SP ACTIVE LOW ACTIVE HIGH S0 = 0 S1 = 0 S0 = 1 S1 = 0 COMBINATORIAL MODE ACTIVE LOW ACTIVE HIGH S0 = 0 S1 = 1 S0 = 1 S1 = 1 4 Specifications ispGAL22V10 ispGAL22V10 LOGIC DIAGRAM / JEDEC FUSE MAP PLCC & SSOP Package Pinout 2 0 4 8 12 16 20 24 28 32 36 40 ASYNCHRONOUS RESET (TO ALL REGISTERS) 0000 0044 . . . 0396 8 OLMC S0 5808 S1 5809 0440 . . . . 0880 10 OLMC S0 5810 S1 5811 3 0924 . . . . . 1452 12 OLMC 27 26 25 S0 5812 S1 5813 4 1496 . . . . . . 2112 14 OLMC 24 S0 5814 S1 5815 5 2156 . . . . . . . 2860 16 OLMC 23 S0 5816 S1 5817 6 2904 . . . . . . . 3608 16 OLMC 21 S0 5818 S1 5819 7 3652 . . . . . . 4268 14 OLMC 20 S0 5820 S1 5821 9 4312 . . . . . 4840 12 OLMC 19 S0 5822 S1 5823 10 4884 . . . . 5324 10 OLMC S0 5824 S1 5825 11 5368 . . . 5720 8 OLMC S0 5826 S1 5827 12 SYNCHRONOUS PRESET (TO ALL REGISTERS) 5764 13 5828, 5829 ...

Once the function is programmed, the non-volatile E2CMOS cells will not lose the pattern even when the power is turned off. ELECTRONIC SIGNATURE An electronic signature (ES) is provided in every ispGAL22V10 device. It contains 64 bits of reprogrammable memory that can contain user-defined data. Some uses include user ID codes, revision numbers, or inventory control. The signature data is always available to the user independent of the state of the security cell. All necessary programming is done via four TTL level logic interface signals. These four signals are fed into the on-chip programming circuitry where a state machine controls the programming. The interface signals are Serial Data In (SDI), Serial Data Out (SDO), Serial Clock (SCLK) and Mode (MODE) control. For details on the operation of the internal state machine and programming of ispGAL22V10 devices please refer to the ISP Architecture and Programming section in this Data Book. The electronic signature is an additional feature not present in other manufacturers' 22V10 devices. To use the extra feature of the user-programmable electronic signature it is necessary to choose a Lattice Semiconductor 22V10 device type when compiling a set of logic equations. In addition, many device programmers have two separate selections for the device, typically an ispGAL22V10 and a ispGAL22V10-UES (UES = User Electronic Signature) or ispGAL22V10-ES. This allows users to maintain compatibility with existing 22V10 designs, while still having the option to use the GAL device's extra feature. OUTPUT REGISTER PRELOAD When testing state machine designs, all possible states and state transitions must be verified in the design, not just those required in the normal machine operations. This is because certain events may occur during system operation that throw the logic into an illegal state (power-up, line voltage glitches, brownouts, etc.). To test a design for proper treatment of these conditions, a way must be provided to break the feedback paths, and force any desired (i.e., illegal) state into the registers. Then the machine can be sequenced and the outputs tested for correct next state conditions. The JEDEC map for the ispGAL22V10 contains the 64 extra fuses for the electronic signature, for a total of 5892 fuses. However, the ispGAL22V10 device can still be programmed with a standard 22V10 JEDEC map (5828 fuses) with any qualified device programmer. The ispGAL22V10 device includes circuitry that allows each registered output to be synchronously set either high or low. Thus, any present state condition can be forced for test sequencing. If necessary, approved GAL programmers capable of executing test vectors perform output register preload automatically. SECURITY CELL A security cell is provided in every ispGAL22V10 device to prevent unauthorized copying of the array patterns. Once programmed, this cell prevents further read access to the functional bits in the device. This cell can only be erased by reprogramming the device, so the original configuration can never be examined once this cell is programmed. The Electronic Signature is always available to the user, regardless of the state of this control cell. INPUT BUFFERS ispGAL22V10 devices are designed with TTL level compatible input buffers. These buffers have a characteristically high impedance, and present a much lighter load to the driving logic than bipolar TTL devices. LATCH-UP PROTECTION All input and I/O pins (except SDI on the ispGAL22V10C) also have built-in active pull-ups. As a result, floating inputs will float to a TTL high (logic 1). The SDI pin on the ispGAL22V10C has a built-in pull-down to keep the device out of the programming state if the pin is not actively driven. However, Lattice Semiconductor recommends that all unused inputs and tri-stated I/O pins be connected to an adjacent active input, Vcc, or ground. Doing so will tend to improve noise immunity and reduce Icc for the device. (See equivalent input and I/O schematics on the following page.) Typical Input Current ispGAL22V10 devices are designed with an on-board charge pump to negatively bias the substrate. The negative bias is of sufficient magnitude to prevent input undershoots from causing the circuitry to latch. Additionally, outputs are designed with nchannel pullups instead of the traditional p-channel pullups to eliminate any possibility of SCR induced latching. DEVICE PROGRAMMING The ispGAL22V10 device uses a standard 22V10 JEDEC fusemap file to describe the device programming information. Any third party logic compiler can produce the JEDEC file for this device. Input Current (µA) 0 IN-SYSTEM PROGRAMMABILITY The ispGAL22V10 device features In-System Programmable technology.

Vcc t su t wl CLK t pr INTERNAL REGISTER Q - OUTPUT Internal Register Reset to Logic "0" ACTIVE LOW OUTPUT REGISTER Device Pin Reset to Logic "1" ACTIVE HIGH OUTPUT REGISTER Device Pin Reset to Logic "0" Circuitry within the ispGAL22V10 provides a reset signal to all registers during power-up. All internal registers will have their Q outputs set low after a specified time (tpr, 1µs MAX). As a result, the state on the registered output pins (if they are enabled) will be either high or low on power-up, depending on the programmed polarity of the output pins. This feature can greatly simplify state machine design by providing a known state on power-up. The timing diagram for power-up is shown below. Because of the asynchronous nature of system power-up, some conditions must be met to provide a valid power-up reset of the ispGAL22V10. First, the Vcc rise must be monotonic. Second, the clock input must be at static TTL level as shown in the diagram during power up. The registers will reset within a maximum of tpr time. As in normal system operation, avoid clocking the device until all input and feedback path setup times have been met. The clock must also meet the minimum pulse width requirements.
