DATASHEET 82C54 FN2970 Rev 6.00 CMOS Programmable Interval Timer Sep 15, 2015 The Intersil 82C54 is a high performance CMOS Features Programmable Interval Timer manufactured using an 8MHz to 12MHz Clock Input Frequency advanced 2 micron CMOS process. Compatible with NMOS 8254 The 82C54 has three independently programmable and - Enhanced Version of NMOS 8253 functional 16-bit counters, each capable of handling clock input frequencies of up to 8MHz (82C54) or 10MHz Three Independent 16-Bit Counters (82C54-10) or 12MHz (82C54-12). Six Programmable Counter Modes The high speed and industry standard configuration of the Status Read Back Command 82C54 make it compatible with the Intersil 80C86, 80C88, Binary or BCD Counting and 80C286 CMOS microprocessors along with many other industry standard processors. Six programmable Fully TTL Compatible timer modes allow the 82C54 to be used as an event Single 5V Power Supply counter, elapsed time indicator, programmable one-shot, and many other applications. Static CMOS circuit design Low Power insures low power operation. - ICCSB .10A - ICCOP 10mA at 8MHz The Intersil advanced CMOS process results in a significant reduction in power with performance equal to or greater than Operating Temperature Ranges existing equivalent products. - CX82C54 . 0C to +70C - IX82C54 .-40C to +85C - MD82C54 .-55C to +125C Pb-Free Plus Anneal Available (RoHS Compliant) Pinouts 82C54 (PDIP, CERDIP) 82C54 (PLCC/CLCC) TOP VIEW TOP VIEW D7 1 24 VCC 4 3 2 1 28 27 26 D6 2 23 WR D5 3 22 RD D4 5 25 NC D4 4 21 CS D3 6 24 CS D3 5 20 A1 D2 7 23 A1 D2 6 19 A0 D1 8 22 A0 D1 7 18 CLK 2 D0 9 21 CLK2 D0 8 17 OUT 2 10 CLK 0 20 OUT 2 CLK 0 9 16 GATE 2 11 NC 19 GATE 2 OUT 0 10 15 CLK 1 GATE 0 11 14 GATE 1 12 13 14 15 16 17 18 GND 12 13 OUT 1 FN2970 Rev 6.00 Page 1 of 23 Sep 15, 2015 OUT 0 D5 GATE 0 D6 GND D7 NC NC OUT 1 VCC GATE 1 WR CLK 1 RD82C54 Ordering Information PART NUMBERS TEMP RANGE PKG. 8MHz 10MHz 12MHz (C) PACKAGE DWG.

They are not intended for use in Reflow solder processing applications. NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. FN2970 Rev 6.00 Page 2 of 23 Sep 15, 2015
