S1D13709F00A100

Video Processing Overview

The S1D13709 is a graphics LCD controller with an embedded 32 KB SRAM display buffer supporting TFT and STN panels. It features an 8-bit CPU data bus, direct/indirect address support, and a programmable hardware cursor. The device includes 160 mask-programmed 5x7 pixel characters in CGROM and up to 256 8x16 pixel characters in CGRAM. It supports resolutions up to 640x240@1bpp for STN and WVGA via up-scaling for TFT. Operating voltage ranges from 3.0V to 5.5V across COREVDD, PLLVDD, NIOVDD, and HIOVDD. The operating temperature range is -40°C to +85°C.

Video Processing Procurement Notes

Verify the specific ordering suffix against official Epson documentation to confirm package type and electrical characteristics. Confirm that the intended application falls within general purpose or designated use categories as specified in the datasheet. Ensure compliance with export regulations if applicable. Contact Epson sales representatives for current availability and latest technical updates before finalizing procurement plans.

Video Processing Selection Notes

Select this component when a functional replacement for the S1D13700 is required for software compatibility. Choose this controller for designs requiring layered text and graphics on STN or TFT panels. Consider the 80-pin QFP package constraints and the need for external crystal or oscillator input. Evaluate power consumption requirements against the supported low power modes and voltage domains.

Video Processing Part Context

The S1D13709 belongs to the S1D137xx series of graphics LCD controllers manufactured by Seiko Epson Corporation. It serves as a direct software-compatible upgrade path from the S1D13700, enabling migration from STN to TFT panel systems without redesigning host software. The device integrates display memory, character generators, and timing signal generation into a single chip.

Video Processing Replacement Considerations

The S1D13709 is designed as a functional replacement for the S1D13700 from a software perspective.
