The 24064 LCD 240×64 T6963C controller module achieves compatibility with RA6963 through shared parallel interface protocols, voltage tolerance, and command structure alignment. Both controllers operate on 5V logic levels and use 8-bit parallel data buses for memory access and display control. Key compatibility factors include matched timing requirements, status flag management (e.g., READY/BUSY), and font/bitmap addressing schemes. Panox Display leverages these overlaps to design modules supporting dual-controller integration for industrial automation clients.
How Does a Flexible Display Screen Function?
What interface protocols enable T6963C-RA6963 compatibility?
The 8-bit parallel interface and busy flag synchronization ensure seamless communication. Both controllers use identical pinouts for data lines (DB0-DB7), reset (RESET), and chip select (CS), enabling hardware-level compatibility. Panox Display modules reinforce this with 10kΩ pull-up resistors on critical control lines like WR (write) and RD (read).
Deep Dive: At the protocol level, both controllers require 500ns minimum pulse widths for read/write operations and share address mapping conventions—text buffers start at 0x0000, graphics at 0x8000. A critical nuance lies in status byte interpretation: T6963C uses bit 0 for command readiness, while RA6963 reserves bit 1 for auto-reset detection. Pro Tip: Implement a unified status-check routine masking non-essential bits. For example, industrial HMIs using 24064 displays often deploy multiplexers to toggle between controllers without hardware reconfiguration. Tables below highlight protocol alignment:
| Signal | T6963C Timing | RA6963 Timing |
|---|---|---|
| CS Low to WR/RD High | 220ns | 200ns |
| Data Setup Time | 100ns | 120ns |
How do memory architectures align across controllers?
Both employ 128KB external RAM addressing with split text/graphics layers. The 24064’s 240×64 pixel grid (15,360 bits) fits within both controllers’ 32KB minimum graphics buffer allocation. Panox Display optimizes this through bank switching logic in their PCBAs.
Deep Dive: The T6963C reserves 2KB for CG-ROM fonts vs. RA6963’s 4KB, but compatibility stems from shared ASCII mapping in the first 256 characters. Practical implementations often disable internal fonts and load unified .HZK files into external RAM. For instance, warehouse inventory systems use Panox Display’s 24064 modules to show barcodes (graphics layer) and item codes (text layer) through either controller. Pro Tip: Allocate separate RAM blocks for each controller when designing dual-mode systems to prevent data corruption.

FAQs
Yes, provided the PCB has matching 34-pin FPC connectors and 5V±5% power rails. Always update initialization routines to handle T6963C’s extended register set.
Why does text appear shifted when switching controllers?
Font width register defaults differ—T6963C uses 6 pixels/character vs. RA6963’s 8 pixels. Reprogram offset parameters in your display driver code.
