256 Ð¥ 8 BIT STATIC CMOS EEPROM WITH I²Ð¡-BUS.
( ANALOG - MICROCIRCUIT PCF8582Е, F.PHILIPS).
INF8582E - 2Кbit (256х8 bit) electronically erasable programmable ROM with
“floating” gate. Internal reduntant code correcting errors as single bit errors is used to
enhance the reliability. Microcircuit operates in systems with serial I²C-bus consisting of
two lines: for data signals (SDA) (bidirectional) and for clock signals (SCL). Up to 8 mi-
crocircuits may be connected to I²C-bus. Stacker programming is done by tunneling
electrons. Programming voltage is generated by voltage multiplier built-in chip. The im-
plementation of CMOS technology in full provides low power consumption.
These products are purposed for implementation in portable consumer applica-
tions, in autoelectronics, in peripheric computer devices. Thea are used in TV chan-
nel selectors, for storage of frequency, volume and image data, in tuning control blocks
in radioset,
, in measuring devices for standard curves storage, calibration data,
minimum and maximum values, in , seat position adgusting systems, side glass, in
speedometers.
Characteristic properties:
- without decay storage 2 Кbit 10 years;
- single-error correction circuit;
- one power supply (Uсс=4,5V - 5,5V);
- built-in voltage multiplier in chip;
- input/output consecutive bus ;
- automatic increment of word address;
- internal timer for recording;
- 100 000 cycles erasure/recording on byte with low failure rate;
- unlimited number of reading cycles;
- low power consumption;
- temperature range -40 - +85 ^ОС.
