ICs for TV-SETS INA2586 1024 x 8-Bit n-MOS EEPROM with I2C-Bus Interface The INA2586 is a 8-Kbit (1024 x 8-bit) n-MOS floating gate electrically erasable programmable read only memory (EEPROM). 2 2 IC works in systems with serial I C-bus. Up to two INA2586 devices may be connected to the I C-bus.The programming of the array is implemented by electron’s tunneling. The programming voltage is generated on-chip, using a voltage multiplier. Device is functionally identical to the SDA2586, Siemens. IC are made in 8-pin DIP and 8-pin SOP. FEATURES ♦ Non-volatile storage of information during 10 years ♦ Single supply (Ucc=4,75 B - 5,25 B) ♦ On-chip voltage multiplier ♦ On-chip generator of bulk biasing 2 ♦ Serial input/output I C-bus ♦ 10 000 ERASE/WRITE cycles per byte; ♦ Internal reprogramming (no external components) ♦ Duration of the ERASE/WRITE cycle is 15 ms 0 ♦ Temperature range: 0 ÷ +70 C ELECTRICAL CHARACTERISTICS Parameter Supply current, mA Output low voltage (SDA), V High leakage current: -on output (SDA), µA -on inputs SCL, SDA, µA -on inputs CS, TP1, TP2,µA Input capacitance, pF Clock input frequency, kHz Reprogramming cycle time, ms Erase of die cycle time, ms The number of E/W cycles on 1 byte Input high voltage: -inputs SDA, SCL, V -inputs CS, TP1, TP2, V Input low voltage: -inputs SDA, SCL, V -inputs CS, TP1, TP2, V Conditions UCC=5.25 B IOL=3 mA UCC=4.75B Symbol ICC0 UOL Min. - Max 20,0 0,4 UOH=5,25 B UIH=5,25 B UIH=5,25 B U I= 0 B ILOH ILIH ILIH CI fSCL Erase and Write UTP2= 5,0 B tPROG tER 0 10,0 10 000 10,0 10,0 100,0 10,0 100 20,0 20,0 - UIH 3,0 4,5 UCC UCC UIL - 1,5 0,2 PIN ASSIGNMENT PIN DESCRIPTION SYMBOL Uss CS TP1 TP2 SDA SCL TP3 Ucc PIN 1 2 3 4 5 6 7 8 Uss DESCRIPTION GND Chip selection Testing pin Testing pin (0V - normal mode, 5V - chip erasing) Informational line, input/output Clock input Testing pin, not connected Supply Voltage Ucc 1 8 CS 2 7 TP3 TP1 3 6 SCL TP2 4 5 SDA 1 INTEGRAL
