ATF1508ASVL-20AU100

Product Summary

The ATF1508ASV(L) is a high-performance, high-density complex programmable logic
device (CPLD) that utilizes Atmel proven electrically-erasable technology. With 128
logic macrocells and up to 100 inputs, it easily integrates logic from several TTL, SSI,
MSI, LSI and classic PLDs.
The ATF1508ASV(L) has up to 96 bi-directional I/O pins and four dedicated input pins,
depending on the type of device package selected. Each dedicated pin can also serve
as a global control signal, register clock, register reset or output enable. Each of these
control signals can be selected for use individually within each macrocell.
Each of the 128 macrocells generates a buried feedback that goes to the global bus.
Each input and I/O pin also feeds into the global bus. The switch matrix in each logic
block then selects 40 individual signals from the global bus. Each macrocell also generates a foldback logic term that goes to a regional bus.Cascade logic between
macrocells in the ATF1508ASV(L) allows fast, efficient generation of complex logic functions. The ATF1508ASV(L) contains eight such logic chains, each capable of creating
sum term logic with a fan-in of up to 40 product terms.
The ATF1508ASV(L) macrocell, shown in Figure 1, is flexible enough to support highlycomplex logic functions operating at high-speed. The macrocell consists of five sections:
product terms and product term select multiplexer, OR/XOR/CASCADE logic, a flip-flop,
output select and enable, and logic array inputs.
Unused macrocells are automatically disabled by the compiler to decrease power consuption-A security fuse,when programmed,protects the contents of the
ATF1508ASV(L). Two bytes (16 bits) of User Signature are accessible to the user for
purposes such as storing project name, part number, revision or date. The User Signature is accessible regardless of the state of the security fuse.
The ATF1508ASV(L) device is an in-system programmable (ISP) device. It uses the
industry-standard 4-pin JTAG interface (IEEE Std. 1149.1), and is fully-compliant with
JTAG Boundary-scan Description Language (BSDL). ISP allows the device to be programmed without removing it from the printed circuit board. In addition to simplifying the
manufacturing flow, ISP also allows design modifications to be made in the field via
software
