AMD XC4005L-5PC84C

Overview

XC4005L-5PC84C from Xilinx is a low-voltage, 3.3 V, third-generation Field-Programmable Gate Array (FPGA) with 5,000 usable logic gates, 196 Configurable Logic Blocks (CLBs), and 112 user I/O pins in an 84-pin plastic leaded chip carrier (PLCC) package. It integrates on-chip Select-RAM memory with synchronous write and dual-port modes, dedicated carry logic, and eight global low-skew clock networks - enabling PCI-compliant 66 MHz system operation in embedded control and digital signal interface applications.

For engineers reviewing the XC4005L-5PC84C datasheet, pinout, applications, or equivalent options, key selection criteria include its 3.3 V supply compatibility, 112-user-I/O count, -5 speed grade timing (T_PD = 5.0 ns CLB-to-CLB), 4 mA output sink capability, and PLCC-84 mechanical footprint for legacy board reuse.

Technical Context

The XC4005L-5PC84C implements a regular array of 14×14 CLBs, each containing two 4-input function generators (F/G), one 3-input H generator, dual edge-triggered D flip-flops, and configurable RAM modes (16×2 single-port, 32×1, or 16×1 dual-port). Its routing hierarchy includes longlines, double-length lines, and segmented interconnects with dedicated carry chains and wide edge decoders on all four sides.

It supports IEEE 1149.1 boundary scan, programmable I/O slew rate, input pull-up/pull-down resistors, and configuration via master/slave serial or parallel modes. The -5 speed grade guarantees 66 MHz system clock performance with 5.0 ns CLB propagation delay and 3.9 ns address decoder delay, meeting full PCI compliance requirements for 33 MHz bus interfacing.

FAQ

What is the operating voltage range for XC4005L-5PC84C?

The XC4005L-5PC84C operates from 3.0 V to 3.6 V DC. This low-voltage specification distinguishes it from the 5 V XC4005E family and enables lower power consumption and reduced switching noise. All I/Os and core logic are designed for this range, and operation outside it may cause functional failure or reliability degradation. The XC4005L-5PC84C must not be powered from a 5 V supply.

Is XC4005L-5PC84C pin-compatible with XC4005E-5PC84C?

Yes, XC4005L-5PC84C is physically pin-compatible with XC4005E-5PC84C - both use the 84-pin PLCC package with identical pin assignments and mechanical dimensions. However, they differ electrically: XC4005L-5PC84C requires 3.3 V and delivers 4 mA per output, while XC4005E-5PC84C uses 5 V and sinks 12 mA. Direct substitution requires voltage level translation or board redesign.

Does XC4005L-5PC84C support boundary scan testing?

Yes, XC4005L-5PC84C includes full IEEE 1149.1-compliant boundary scan logic with TDI, TDO, TCK, TMS, and TRST pins implemented per the PLCC-84 pinout. This enables automated PCB test, interconnect verification, and in-system programming without physical probe access. The boundary scan chain covers all user I/Os and internal configuration logic, and is supported by Xilinx development tools.

What configuration modes does XC4005L-5PC84C support?

XC4005L-5PC84C supports five configuration modes: Master Serial, Slave Serial, Master Parallel, Slave Parallel, and JTAG (boundary scan). Configuration is initiated via M0/M1/M2 pins at power-up. Slave Serial is the most common, using CCLK and DIN; Master Parallel allows fastest loading via 8-bit parallel bus. All modes retain full readback capability for bitstream verification.

Can XC4005L-5PC84C implement dual-port RAM functions?

Yes, XC4005L-5PC84C can configure any CLB's function generators as true dual-port RAM (16×1), enabling simultaneous independent read and write operations on separate ports. This is achieved by dedicating F and G generators to separate address/data paths, with no shared timing constraints. Each of the 196 CLBs supports this mode, providing up to 3,136 bits of dual-port RAM - sufficient for small FIFOs or register files without external memory.
