General Description
The LS0144T10-M-V1 is an economical and compact display module built around a standard TN panel. Its 1.44-inch square format with 128x128 resolution is suitable for displaying icons, simple graphics, or text status. The module is controlled by the NV3023B driver IC via an 8-bit 8080 parallel interface.
The specification provides a detailed pin description for its 24-pin connector, which interestingly interleaves data bits (D0-D7) with NC (No Connection) pins. It includes comprehensive 8080 parallel interface timing characteristics for both asynchronous write and read modes, with defined minimum values for critical parameters like write cycle (T_WC=80ns), read cycle for ID (T_RC=160ns), and data setup/hold times (T_DST/T_DHT=10ns). A dedicated reset timing section provides crucial details on valid reset pulse width (min 10us), reset completion time (max 5ms in Sleep-In, 120ms in Sleep-Out), and spike rejection logic.
