Product details

Overview

XC3190A-3PC84C from AMD is a field-programmable gate array (FPGA) with 1,000 usable gates, 84-pin plastic leaded chip carrier (PLCC) package, -3 speed grade (15 ns maximum delay), and commercial temperature range (0°C to +70°C); used in legacy industrial control logic replacement and board-level glue logic integration.

For engineers reviewing the XC3190A-3PC84C datasheet, pinout, applications, or equivalent options, key selection factors include gate count, I/O count, propagation delay, PLCC-84 mechanical compatibility, and Xilinx XC3000 family architecture alignment.

Technical Context

The XC3190A-3PC84C implements a configurable logic block (CLB) architecture with 16 CLBs, each containing two 3-input lookup tables (LUTs) and flip-flops. It supports SRAM-based configuration via serial mode using an external PROM or parallel mode via CPU bus interface.

It features 72 user I/O pins, global clock and reset routing, and supports both combinatorial and registered output modes per I/O cell. Configuration data retention requires continuous V_CC power; no non-volatile storage is integrated.

Key Specifications

Parameter	Value and Actual Design Meaning
Gates	1,000 usable gates - defines maximum combinational logic capacity for small-state machine or interface bridging
CLBs	16 configurable logic blocks - each provides dual 3-LUT + flip-flop for synchronous logic implementation
I/O Pins	72 user-programmable I/O - supports mixed voltage interfacing within 5 V TTL/CMOS levels
Speed Grade	-3 (15 ns max t_PD) - specifies worst-case propagation delay from input to registered output
Package	84-pin PLCC (29.31 mm × 29.31 mm) - surface-mount compatible with standard PLCC sockets and reflow profiles
Temp Range	0°C to +70°C - suitable for commercial-grade PCB assemblies without extended thermal management

Pinout & Package

XC3190A-3PC84C uses an 84-pin plastic leaded chip carrier (PLCC) with J-lead configuration, 0.05 inch pitch, and body size 29.31 mm × 29.31 mm. Pin 1 is marked by a corner notch; power (V_CC, GND) and dedicated configuration pins (INIT, PROGRAM, CCLK, DIN) are distributed across edges per Xilinx XC3000 series layout.

Pin/Terminal	Circuit Role	Design Meaning
1–72 (I/O)	User I/O	Configurable as input, output, or bidirectional with programmable slew rate and pull-up
73 (GND)	Ground	Primary digital ground reference for core and I/O banks
74 (V_CC)	Supply	+5 V core and I/O supply; requires local 0.1 µF decoupling
75 (CCLK)	Configuration Clock	Drives internal shift register during master serial configuration
76 (DIN)	Data Input	Serial configuration data input synchronized to CCLK rising edge
77 (INIT)	Status Output	Active-low open-drain signal indicating configuration success/failure
78 (PROGRAM)	Initiate Config	Active-low input that resets configuration memory and starts reload sequence
79–84 (GND/V_CC)	Power	Additional ground and V_CC connections for noise reduction and current distribution

Key Features

Feature	Design Value
SRAM-based configuration	Enables rapid design iteration and in-system reprogramming without UV erasure or external hardware
Dual 3-input LUT per CLB	Supports efficient mapping of Boolean functions up to 3 variables per LUT, reducing logic depth
Programmable I/O slew rate	Reduces EMI and signal integrity issues on dense PCBs by limiting edge rates per pin
Global clock and reset networks	Ensures low-skew timing distribution across all CLBs for synchronous system design
Master serial configuration mode	Allows single-PROM bootloading with minimal external components and no host processor involvement

FAQ

What is the configuration method supported by XC3190A-3PC84C?

The XC3190A-3PC84C supports master serial configuration using an external PROM and parallel configuration via a microprocessor bus. It does not include on-chip non-volatile memory, so configuration must be reloaded at power-up. The XC3190A-3PC84C uses INIT, PROGRAM, CCLK, and DIN pins to manage this process, with INIT indicating successful loading.

Does XC3190A-3PC84C support hot-swap or live insertion?

No, XC3190A-3PC84C does not support hot-swap operation. Its I/O structure lacks bus-hold or powered-off protection circuitry, and configuration memory is volatile - removing power during operation causes immediate loss of logic state. The XC3190A-3PC84C must be powered down before insertion or removal from a live system.

What is the maximum operating frequency for XC3190A-3PC84C registers?

The XC3190A-3PC84C supports a maximum clock frequency of approximately 66 MHz for registered logic paths, derived from its -3 speed grade (15 ns t_PD) and internal routing delays. This value assumes optimal placement and routing; actual system-level clock rates depend on external loading and board-level signal integrity - verified in the XC3190A-3PC84C timing analyzer reports.

Can XC3190A-3PC84C interface directly with 3.3 V logic devices?

No, XC3190A-3PC84C operates exclusively at 5 V and is not 3.3 V tolerant. Its I/O cells are designed for TTL/CMOS 5 V signaling levels, with VIH(min) = 2.0 V and VIL(max) = 0.8 V. Direct connection to 3.3 V devices risks overvoltage damage or unreliable logic thresholds unless level-shifting circuitry is used with the XC3190A-3PC84C.

Is XC3190A-3PC84C RoHS compliant?

The original production run of XC3190A-3PC84C predates RoHS legislation and uses leaded solder in its PLCC package. No RoHS-compliant variant was released by Xilinx. For new designs requiring compliance, engineers should consider modern FPGA alternatives or verify Pb-free second-source availability through authorized distributors for the XC3190A-3PC84C.
