Pin Connections; St24Lc21; Description; Features - Hitachi 32LD8700C Service Manual

1000-V Charged-Device Model (C101)

• Supports Both Digital and Analog Applications: USB Interface, Differential Signal Interface, Bus

Isolation, Low-Distortion Signal Gating

11.24.3.

11.25.1.

The ST24LC21 is a 1K bit electrically erasable programmable memory (EEPROM), organized by 8 bits.

This device can operate in two modes: Transmit Only mode and I

the device is in Transmit Only mode with EEPROM data clocked out from the rising edge of the signal

applied on VCLK. The device will switch to the I

applied on SCL pin. The ST24LC21 can not switch from the I

mode (except when the power supply is removed). The device operates with a power supply value as

low as 2.5V. Both Plastic Dual-in-Line and Plastic Small Outline packages are available.
