ICM7211AMIPLZ Datasheet PDF - Renesas Electronics

●The ICM7211AMIPLZ is a 4-digit LCD Display Driver. The ICM7211AM device is a non-multiplexed four-digit seven-segment CMOS LCD display decoder-driver. This device is configured to drive conventional LCD displays by providing a complete RC oscillator, divider chain, backplane driver and 28 segment outputs. It also has a microprocessor compatible input configuration, which provides data input latches and Digit Address latches under control of high-speed Chip Select inputs. These devices simplify the task of implementing a cost-effective alphanumeric seven-segment display for microprocessor systems, without requiring extensive ROM or CPU time for decoding and display updating. The ICM7211AM provides the "Code B" output code, i.e., 0-9, dash, E, H, L, P, blank, but will correctly decode true BCD to seven-segment decimal outputs. Provides data and digit address latches controlled chip select inputs to provide a direct high speed processor interface.

● Four digit non-multiplexed 7 segment LCD display outputs with backplane driver

● Complete onboard RC oscillator to generate backplane frequency

● Backplane input/output allows simple synchronization slave-devices to a master

● Decodes binary to code B (0-9, Dash, E, H, L, P, blank)
