Based on silicon gate CMOS technology, it requires a standby current of only 100 mA (max.) when the chip is in the nonselected state. During timer operation, power consumption is still very low only 8 mA (max.).

E2O0018-27-X2 ¡ Semiconductor¡ Semiconductor MThSiMs v8e2rCsi5o3n-:2JRaSn/. G19S9/8JS Previous version: Aug. 1996 MSM82C53-2RS/GS/JS CMOS PROGRAMMABLE INTERVAL TIMER GENERAL DESCRIPTION The MSM82C53-2RS/GS/JS is programmable universal timers designed for use in microcomputer systems. Based on silicon gate CMOS technology, it requires a standby current of only 100 mA (max.) when the chip is in the nonselected state. During timer operation, power consumption is still very low only 8 mA (max.) at 8 MHz of current required. The device consists of three independent counters, and can count up to a maximum of 8 MHz (MSM82C53-2). The timer features six different counter modes, and binary count/BCD count functions. Count values can be set in byte or word units, and all functions are freely programmable. FEATURES • Maximum operating frequency of 8 MHz (MSM82C53-2) • High speed and low power consumption achieved through silicon gate CMOS technology • Completely static operation • Three independent 16-bit down-counters • 3 V to 6 V single power supply • Six counter modes available for each counter • Binary and decimal counting possible • 24-pin Plastic DIP (DIP24-P-600-2.54): (Product name: MSM82C53-2RS) • 28-pin Plastic QFJ (QFJ28-P-S450-1.27): (Product name: MSM82C53-2JS) • 32-pin Plastic SSOP(SSOP32-P-430-1.00-K): (Product name: MSM82C53-2GS-K) 1/19 ¡ Semiconductor FUNCTIONAL BLOCK DIAGRAM VCC GND 8 Data D7 - D0 Bus Buffer WR RD Read/ Write A0 Logic A1 CS 8 Control Word Register MSM82C53-2RS/GS/JS Counter #0 CLK0 GATE0 OUT0 Counter #1 CLK1 GATE1 OUT1 Counter #2 CLK2 GATE2 OUT2 Internal Bus 2/19 ¡ Semiconductor PIN CONFIGURATION (TOP VIEW) 24 pin Plastic DIP D7 1 D6 2 D5 3 D4 4 D3 5 D2 6 D1 7 D0 8 CLK0 9 OUT0 10 GATE0 11 GND 12 32 pin Plastic SSOP NC D7 D6 D5 NC D4 D3 D2 D1 D0 CLK0 NC OUT0 GATE0 GND NC 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 28 pin Plastic QFJ D4 5 D3 6 D2 7 D1 8 D0 9 CLK0 10 NC 11 OUT0 12 GATE0 13 GND 14 NC 15 OUT1 16 GATE1 17 CLK1 18 4 D5 3 D6 2 D7 1 NC 28 VCC 27 WR 26 RD MSM82C53-2RS/GS/JS 24 Vcc 23 WR 22 RD 21 CS 20 A1 19 A0 18 CLK2 17 OUT2 16 GATE2 15 CLK1 14 GATE1 13 OUT1 32 NC 31 Vcc 30 WR 29 RD 28 NC 27 CS 26 A1 25 A0 24 CLK2 23 OUT2 22 GATE2 21 NC 20 CLK1 19 GATE1 18 OUT1 17 NC (NC denotes "not connected") 25 NC 24 CS 23 A1 22 A0 21 CLK2 20 OUT2 19 GATE2 3/19 ¡ Semiconductor MSM82C53-2RS/GS/JS ABSOLUTE MAXIMUM RATINGS Parameter Supply Voltage Input Voltage Output Voltage Storage Temperature Power Dissipation Symbol VCC VIN VOUT TSTG PD Condition Respect to GND — Ta = 25°C Rating MSM82C53-2RS MSM82C53-2GS MSM82C53-2JS –0.5 to + 7 –0.5 to VCC + 0.5 –0.5 to VCC + 0.5 –55 to + 150 0.9 0.7 0.9 Units V V V °C W OPERATING RANGES Parameter Supply Voltage Operating Temperature Symbol VCC Top Condition VIL = 0.2 V, VIH = VCC -0.2 V, Operating Frequency 2.6 MHz Range 3 to 6 –40 to +85 Unit V °C RECOMMENDED OPERATING CONDITIONS Parameter Supply Voltage Operating Temperature "L" Input Voltage "H" Input Voltage Symbol VCC Top VIL VIH Min. 4.5 –40 –0.3 2.2 Typ. 5 +25 — — Max. 5.5 +85 +0.8 VCC + 0.3 Unit V °C V V DC CHARACTERISTICS Parameter "L" Output Voltage "H" Output Voltage Input Leak Current Output Leak Current Standby Supply Current Operating Supply Current Symbol VOL VOH ILI ILO ICCS ICC Condition IOL = 4 mA IOH = –1 mA 0 £ VIN £ VCC 0 £ VOUT £ VCC CS ≥ VCC - 0.2 V VIH ≥ VCC - 0.2 V VIL £ 0.2 V tCLK = 125 ns CL = 0 pF VCC = 4.5 V to 5.5 V Ta = –40°C to +85°C Min. — 3.7 –10 –10 Typ.
