The ATF2500C is organized around a single universal array. All pins and feedback terms are
always available to every macrocell. Each of the 38 logic pins are array inputs, as are the out­puts of each flip-flop.

In the ATF2500C, four product terms are input to each sum term. Furthermore, each macro­cell’s three sum terms can be combined to provide up to 12 product terms per sum term with
no performance penalty. Each flip-flop is individually selectable to be either D- or T-type, pro­viding further logic compaction. Also, 24 of the flip-flops may be bypassed to provide internal
combinatorial feedback to the logic array.

Product terms provide individual clocks and asynchronous resets for each flip-flop. The flip­flops may also be individually configured to have direct input pin clocking. Each output has its
own enable product term. Eight synchronous preset product terms serve local groups of either
four or eight flip-flops. Register preload functions are provided to simplify testing. All registers
automatically reset upon power-up.

The Atmel-unique “L” low-power feature is an edge-sensing option that is now field program­mable for the ATF2500C family. The “L” feature utilizes Atmel-patented Input Transition
Detection (ITD) circuitry and is activated by selecting the “L” option from the program menu.

Using the ATF2500C Family’s Many Advanced Features

The ATF2500Cs advanced flexibility packs more usable gates into 44 leads than other PLDs.
Some of the ATF2500Cs key features are:

• Fully Connected Logic Array – Each array input is always available to every product
term. This makes logic placement a breeze.

• Selectable D- and T-Type Registers – Each ATF2500C flip-flop can be individually
configured as either D- or T-type. Using the T-type configuration, JK and SR flip-flops are
also easily created. These options allow more efficient product term usage.

• Buried Combinatorial Feedback – Each macrocell’s Q2 register may be bypassed to
feed its input (D/T2) directly back to the logic array. This provides further logic expansion
capability without using precious pin resources.

• Selectable Synchronous/Asynchronous Clocking – Each of the ATF2500Cs flip-flops
has a dedicated clock product term. This removes the constraint that all registers use the
same clock. Buried state machines, counters and registers can all coexist in one device
while running on separate clocks. Individual flip-flop clock source selection further allows
mixing higher performance pin clocking and flexible product term clocking within one
design.

• A Total of 48 Registers – The ATF2500C provides two flip-flops per macrocell – a total of

48. Each register has its own clock and reset terms, as well as its own sum term.

• Independent I/O Pin and Feedback Paths – Each I/O pin on the ATF2500C has a
dedicated input path. Each of the 48 registers has its own feedback term into the array as
well. These features, combined with individual product terms for each I/O’s output enable,
facilitate true bi-directional I/O design.

• Combinable Sum Terms – Each output macrocell’s three sum terms may be combined
into a single term. This provides a fan in of up to 12 product terms per sum term with no

speed penalty.

Preload and Observability of Registered Outputs

The ATF2500Cs registers are provided with circuitry to allow loading of each register asyn­chronously with either a high or a low. This feature will simplify testing since any state can be
forced into the registers to control test sequencing. A V

The PRELOAD state is entered by placing an 10.25V to 10.75V signal on SMP lead 42. When
the preload clock SMP lead 23 is pulsed high, the data on the I/O pins is placed into the 12
registers chosen by the Q select and even/odd select pins.

Register 2 observability mode is entered by placing an 10.25V to 10.75V signal on pin/lead 2.

Security Fuse Usage

Input and I/O Pull-ups

All family members of the ATF2500C can be designed with Atmel-Synario™ and Atmel-Win-

™

CUPL

Additionally, the ATF2500C may be programmed to perform the ATV2500H/Ls functional sub­set (no T-type flip-flops, pin clocking or D/T2 feedback) using the ATV2500H/L JEDEC file. In
this case, the ATF2500C becomes a direct replacement or speed upgrade for the
ATV2500H/L. The ATF2500CQ/CQL are direct replacements for the ATV2500BQ/BQL and
the AT2500H/L, including the lack of extra grounds on P4 and P26.

A single fuse is provided to prevent unauthorized copying of ATF2500C fuse patterns. Once
programmed, the outputs will read programmed during verify.

The security fuse should be programmed last, as its effect is immediate.

The security fuse also inhibits Preload and Q2 observability.

All ATF2500C family members have programmable internal input and I/O pinkeeper circuits.

The default condition, including when using the AT2500CQ/CQL family to replace the
AT2500BQ/BQL or AT2500H/L, is that the pinkeepers are not activated.

When pinkeepers are active, inputs or I/Os not being driven externally will maintain their last
driven state. This ensures that all logic array inputs and device outputs are known states.
Pinkeepers are relatively weak active circuits that can be easily overridden by TTL-compatible
drivers (see input and I/O diagrams below).

. ProChip™ designer support will be available Q102.

Functional Logic Diagram Description

INPUT

The ATF2500C functional logic diagram describes the interconnections between the input,
feedback pins and logic cells. All interconnections are routed through the single global bus.

The ATF2500Cs are straightforward and uniform PLDs. The 24 macrocells are numbered 0
through 23. Each macrocell contains 17 AND gates. All AND gates have 172 inputs. The five
lower product terms provide AR1, CK1, CK2, AR2, and OE. These are: one asynchronous
reset and clock per flip-flop, and an output enable. The top 12 product terms are grouped into
three sum terms, which are used as shown in the macrocell diagrams.

Eight synchronous preset terms are distributed in a 2/4 pattern. The first four macrocells share
Preset 0, the next two share Preset 1, and so on, ending with the last two macrocells sharing
Preset 7.

The 14 dedicated inputs and their complements use the numbered positions in the global bus
as shown. Each macrocell provides six inputs to the global bus: (left to right) feedback F2
true and false, flip-flop Q1 true and false, and the pin true and false. The positions occupied by
these signals in the global bus are the six numbers in the bus diagram next to each macrocell.

Note: 1. Either the flip-flop input (D/T2) or output (Q2) may be fed back in the ATF2500Cs.
