Product Overview
RA8835P3N is RAiO’s dot‑matrix graphic LCD controller for monochrome panels, supporting text, graphic and mixed display up to 640×256 dots. It is pin‑compatible with SED1335 / S1D13700 for drop‑in hardware upgrade. Equipped with 8‑bit 8080/6800 MCU interface, built‑in CGROM and up to 64KB external SRAM, it reduces host‑MCU load for industrial, medical and metering display projects.
Core Advantages
Flexible Display & High Resolution
Supports text, graphic and overlay mixed modes, max resolution up to 640×256 dots for monochrome LCD design.
Excellent Hardware Compatibility
Pin‑to‑pin & software compatible with SED1335 / S1D13700, easy legacy‑system migration and upgrade.
On‑board Character Generator ROM
Built‑in 160‑char ASCII CGROM plus CGRAM, lowers MCU workload for text rendering.
Wide‑Voltage Universal Interface
Works with 8080 / 6800 8‑bit MCU bus, wide 2.7‑5.5V supply range for embedded low‑power applications.

Frequently Asked Questions
Q1: What is the main function of RA8835P3N?
A: RA8835P3N is a dot‑matrix graphic LCD controller for monochrome LCD panels, supporting max 640×256 display. External column driver IC is required for LCD driving.
Q2: Can RA8835P3N replace SED1335 or S1D13700?
A: Yes. It is pin‑to‑pin and software compatible for most projects. Minor software timing adjustment may be required for some old legacy boards.
Q3: What MCU interfaces does RA8835P3N support?
A: 8‑bit parallel bus, configurable for either 8080‑series or 6800‑series microcontrollers.
Q4: What is the difference between RA8835P3N and RA8835AP3N?
A: RA8835P3N: PQFP‑60, standard temperature ‑20℃~+70℃. RA8835AP3N: TQFP‑60 industrial grade, ‑40℃~+85℃. Footprints are not compatible, direct swap without PCB change is not allowed.
Q5: Does RA8835P3N integrate on‑chip display RAM?
A: No. External SRAM chip is mandatory, maximum supports up to 64KB external frame‑buffer SRAM.
Q6: Does RA8835P3N include LCD high‑voltage driving circuit?
A: No. This chip only generates display data signal. You need additional external LCD driver IC to bias and drive the LCD glass panel.
Q7: Where can I get datasheet and bulk quotation?
A: Submit your request via our Quick Inquiry form for datasheet, pinout diagram, stock status and volume pricing.
