S1D13706F00A2 - QVGA LCD Controller, 80KB SRAM | Epson
MPN: S1D13706F00A2 ✓ فعالS1D13706F00A2 نمای کلی
A QVGA LCD controller is a graphics display controller IC that drives small-format TFT/STN panels (typically 320x240 pixels) from an embedded memory buffer. It belongs to the broader hierarchy of video processing ICs -> display controllers -> LCD graphics controllers -> power-management-conscious embedded display silicon. By integrating frame memory and timing logic, it removes the need for an external VRAM and timing-control IC, which simplifies PCB design and reduces BOM cost.
Key features include direct support for Epson D-TFD and Sharp HR-TFT panels (a unique feature that eliminates the external Timing Control IC); 80 KB embedded SRAM supporting up to 320x240 at 8 bpp; support for color and monochrome TFT/STN panels; a flexible CPU host interface (typically 8/16-bit); low-power 3.3 V core operation; and 100-pin TQFP packaging suitable for industrial temperature ranges. The integrated timing controller functionality is what differentiates this part from generic QVGA controllers.
Architecturally, the S1D13706 uses an internal 80 KB SRAM display buffer that the CPU host writes into, with the controller's timing logic continuously refreshing the LCD panel. The die integrates the panel timing generator, frame buffer, host bus interface, and power sequencing - allowing direct connection to advanced TFT panels that normally require a separate timing controller.
Typical applications include handheld industrial terminals, portable measurement instruments, embedded HMI panels, medical point-of-care displays, in-vehicle infotainment sub-displays, and low-cost consumer electronics with small QVGA color panels. Its low power consumption makes it particularly suited to battery-operated designs.
When designing with this part, note that the 80 KB SRAM limits color depth at higher resolutions. At 320x240 with 8 bpp the buffer fills completely, so 16 bpp requires careful mode configuration. The host interface timing must match the chosen CPU or microcontroller bus characteristics for reliable frame updates.

کاربردهای معمول
S1D13706F00A2 مناسب است برای 6 کاربردs: Handheld Industrial Terminal, Portable Measurement Instrument, Embedded HMI Panel, Medical Point-of-Care Display, In-Vehicle Infotainment Sub-Display, Low-Cost Consumer Electronics with QVGA Panel.
Handheld Industrial Terminal
The S1D13706F00A2 fits handheld industrial terminals because it drives a 320x240 QVGA TFT panel at 8 bpp from its integrated 80 KB SRAM, eliminating an external frame buffer. The 3.3 V low-power operation suits battery-powered HMI devices, and the 100-pin TQFP (14x14 mm) footprint keeps the display subsystem compact inside ruggedized enclosures. Unlike generic QVGA controllers, the part's direct Epson D-TFD and Sharp HR-TFT interface removes the need for a separate timing controller IC, cutting BOM cost and PCB area in field-service terminals.
پیشنهادی
Portable Measurement Instrument
Portable measurement instruments benefit from the S1D13706F00A2's 80 KB embedded display buffer and direct D-TFD/HR-TFT panel interface. At 320x240 with 8 bpp the buffer holds a full frame, allowing smooth real-time waveform or numeric readouts without external VRAM. The 100-pin TQFP package is well-suited to compact 4-wire resistive or capacitive touch panel assemblies, and the 3.3 V supply matches low-power portable instrument rails. Compared to software-rendered bitmaps on a host MCU, this controller offloads display refresh, freeing the host to handle ADC sampling and signal processing.
پیشنهادی
Embedded HMI Panel
The S1D13706F00A2 is well-matched to embedded HMI panels needing a color QVGA display with simple host integration. Its 8/16-bit CPU bus interface lets it pair with low-cost microcontrollers such as the PIC32MX family, while the 80 KB display buffer holds full-screen menus and process graphics at 8 bpp. Direct Sharp HR-TFT compatibility simplifies sourcing compatible LCD modules, and the 100-TQFP (14x14 mm) package fits standard 4-wire touch screen assemblies. The integrated timing controller functionality reduces design complexity versus two-chip solutions.
پیشنهادی
Medical Point-of-Care Display
Medical point-of-care devices benefit from the S1D13706F00A2's low-power 3.3 V operation, integrated timing controller, and 80 KB embedded SRAM. The QVGA 320x240 resolution at 8 bpp is sufficient for numeric vital-sign readouts, simple waveforms, and icon-based menus common in handheld diagnostics. The 100-pin TQFP package supports clean PCB layouts with isolation between analog signal chains and the digital display subsystem, and Epson's mature display controller family provides the long-term supply stability required for medical equipment life-cycles.
پیشنهادی
In-Vehicle Infotainment Sub-Display
The S1D13706F00A2 can drive small QVGA color sub-displays in vehicle infotainment systems, such as climate control readouts or rear-seat entertainment panels. Its direct Sharp HR-TFT interface suits many automotive-grade panel modules, and the integrated timing controller reduces the digital component count in space-constrained center-stack designs. The 80 KB SRAM supports 8 bpp graphics including icons, gauges, and simple animations. Note that for full automotive AEC-Q100 qualification, designers should verify the specific date code and confirm with Epson's automotive product line.
پیشنهادی
Low-Cost Consumer Electronics with QVGA Panel
Consumer products like simple home appliances, e-readers, and portable gaming devices benefit from the S1D13706F00A2's BOM-saving integration: 80 KB SRAM plus integrated timing controller eliminate two external ICs. The QVGA 320x240 at 8 bpp is more than adequate for status displays, simple game graphics, and menu UIs. The 100-TQFP package and 3.3 V supply match cost-sensitive designs where board area and BOM count directly affect retail price points. Designers can reuse the same firmware driver across the S1D13706F00A2 and S1D13706F00A200 date-code variants for supply flexibility.

یادداشت‌های طراحی
Estimated: at 3.3 V core supply and typical QVGA 320x240 8 bpp refresh operation, the S1D13706F00A2 draws on the order of tens of mW depending on panel load. For battery-powered designs, place a 100 nF ceramic decoupling capacitor as close as possible to each VDD pin and a bulk 10 uF near the package; this stabilizes the core logic against panel-driver inrush when switching between landscape and portrait modes.
Route the parallel host data bus (DB0-DB7) and address bus (AB0-AB15) with matched lengths and a ground reference to keep skew within one host clock period. Keep the panel output lines (R0-R5, G0-G5, B0-B5, FP, LP, SP) short and isolated from the host bus to minimize crosstalk into the analog pixel domain. Place the 100-TQFP decoupling network on the same layer as the IC, directly under the power pins.
The panel interface lines (FP, LP, SP) carry high-speed edge transitions; series-terminate them with 22-33 ohm resistors close to the S1D13706F00A2 if the panel flex cable exceeds roughly 50 mm. Avoid running the panel data bus adjacent to noisy switching power traces; use a guard ground via fence around the panel connector area to reduce EMI into the LCD flex.
Do not assume the 80 KB SRAM supports 16 bpp full-screen double-buffering - it does not. Configure the part for 8 bpp or use partial-screen update. Always tie TEST pins per the datasheet; floating test pins can cause unpredictable display artifacts. Confirm the host bus timing parameters (CS/WR/RD setup/hold) against the chosen MCU's bus cycle in the family datasheet.
