| Philips Semiconductors Programmable Logic Devices Product specification PAL devices 16L8, 16R8, 16R6, 16R4 PLUS16R8D/-7 SERIES FEATURES * Ultra high-speed - tPD = 7.5ns and fMAX = 74MHz for the PLUS16R8-7 Series - tPD = 10ns and fMAX = 60 MHz for the PLUS16R8D Series DESCRIPTION The Philips Semiconductors PLUS16XX family consists of ultra high-speed 7.5ns and 10ns versions of Series 20 PAL devices. The PLUS16XX family is 100% functional and pin-compatible with the 16L8, 16R8, 16R6, and 16R4 Series devices. The sum of products (AND-OR) architecture is comprised of 64 programmable AND gates and 8 fixed OR gates. Multiple bidirectional pins provide variable input/output pin ratios. Individual 3-State control of all outputs and registers with feedback (R8, R6, R4) is also provided. Proprietary designs can be protected by programming the security fuse. The PLUS16R8, R6, and R4 have D-type flip-flops which are loaded on the Low-to-High transition of the clock input. In order to facilitate state machine design and testing, a power-up reset function has been incorporated into these devices to reset all internal registers to Active-Low after a specific period of time. The Philips Semiconductors State-of-the-Art oxide isolation Bipolar fabrication process is employed to achieve high-performance operation. The PLUS16XX family of devices are field programmable, enabling the user to quickly generate custom patterns using standard programming equipment. See the programmer chart for qualified programmers. The SNAP software package from Philips Semiconductors supports easy design entry for the PLUS16XX series as well as other PLD devices from Philips Semiconductors. The PLUS16XX series are also supported by other standard CAD tools for PAL-type devices. Order codes are listed in the Ordering Information table. * 100% functionally and pin-for-pin compatible with industry standard 20-pin PAL(R) ICs * Power-up reset function to enhance state machine design and testability * Design support provided via SNAP and other CAD tools for Series 20 PAL devices * Field-programmable on industry standard programmers * Security fuse * Individual 3-State control of all outputs DEVICE NUMBER PLUS16L8 PLUS16R8 PLUS16R6 PLUS16R4 DEDICATED INPUTS 10 8 8 8 COMBINATORIAL OUTPUTS 8 (6 I/O) 0 2 I/O 4 I/O REGISTERED OUTPUTS 0 8 6 4 ORDERING INFORMATION DESCRIPTION ORDER CODE PLUS16R8DN PLUS16R6DN PLUS16R4DN PLUS16L8DN PLUS16R8-7N PLUS16R6-7N PLUS16R4-7N PLUS16L8-7N PLUS16R8DA PLUS16R6DA PLUS16R4DA PLUS16L8DA PLUS16R8-7A PLUS16R6-7A PLUS16R4-7A PLUS16L8-7A DRAWING NUMBER 20-Pin Plastic Dual-In-Line 300mil-wide 0408B 20-Pin Plastic Leaded Chip Carrier (PLCC) 0400E NOTE: The PLUS16XX series of devices are also processed to military requirements for operation over the military temperature range.

September 10, 1993 42 Philips Semiconductors Programmable Logic Devices Product specification PAL devices 16L8, 16R8, 16R6, 16R4 PLUS16R8D/-7 SERIES FUNCTIONAL DESCRIPTIONS The PLUS16XX series utilizes the familiar sum-of-products implementation consisting of a programmable AND array and a fixed OR array. These devices are capable of replacing an equivalent of four or more SSI/MSI integrated circuits to reduce package count and board area occupancy, consequently improving reliability and design cycle over Standard Cell or gate array options. By programming the security fuse, proprietary designs can be protected from duplication. The PLUS16XX series consists of four PAL-type devices. Depending on the particular device type, there are a variable number of combinatorial and registered outputs available to the designer. The PLUS16L8 is a combinatorial part with 8 user configurable outputs (6 bidirectional), while the other three devices, PLUS16R8, PLUS16R6, PLUS16R4, have respectively 8, 6, and 4 output registers. use a product term to control the enable function. Programmable Bidirectional Pins The PLUS16XX products feature variable Input/Output ratios. In addition to 8 dedicated inputs, each combinatorial output pin of the registered devices can be individually programmed as an input or output. The PLUS16L8 provides 10 dedicated inputs and 6 Bidirectional I/O lines that can be individually configured as inputs or outputs. series are supported by SLICE, the PC-based software development tool from Philips Semiconductors. The PLUS16XX family of devices are also supported by standard CAD tools for PAL devices, including ABEL and CUPL. SLICE is available free of charge to qualified users. Logic Programming The PLUS16XX series is fully supported by industry standard (JEDEC compatible) PLD CAD tools, including Philips Semiconductors SNAP design software package. ABELTM CUPLTM and PALASM(R) 90 design software packages also support the PLUS16XX architecture. All packages allow Boolean and state equation entry formats. SNAP, ABEL and CUPL also accept, as input, schematic capture format. Output Registers The PLUS16R8 has 8 output registers, the 16R6 has 6, and the 16R4 has 4. Each output register is a D-type flip-flop which is loaded on the Low-to-High transition of the clock input. These output registers are capable of feeding the outputs of the registers back into the array to facilitate design of synchronous state machines. Power-up Reset 3-State Outputs The PLUS16XX series devices also feature 3-State output buffers on each output pin which can be programmed for individual control of all outputs. The registered outputs (Qn) are controlled by an external input (/OE), and the combinatorial outputs (On, Bn) By resetting all flip-flops to a logic Low, as the power is turned on, the PLUS16R8, R6, R4 enhance state machine design and initialization capability.
