概述

Description

MAX7450ESA+T is Maxim’s MAX7450 On-Screen Display (OSD) / video overlay controller in the ESA package, shipped in tape-and-reel (T). It adds text, graphics, and bitmaps onto a video signal (NTSC/PAL) with minimal host processing. Key points:
- OSD/graphics overlay on video; supports fonts and bitmaps with color control
- Serial control interface (SPI-like) to load fonts, bitmaps, and display parameters
- Suitable for automotive cameras, security/video, set-top boxes, etc.
- Typically used with a microcontroller that supplies overlay data (text, status, time/date, navigation info)
The ESA+T suffix just denotes the package type and reel packaging, not a feature set. For exact pinout, electrical specs, timing, and register map, refer to the MAX7450 datasheet.

Features

Here are the key features of MAX7450ESA+T (OSD controller):
- Monochrome on-screen display (OSD) overlay generator for video
- NTSC and PAL video compatibility
- Built-in font ROM with alphanumeric and symbol characters; support for additional/custom fonts
- Text and graphics overlay with programmable X/Y position and size
- Serial control interface (SPI-like) for real-time configuration via a register map
- Multiple OSD windows/layers with priority control
- Transparency/background options and non-destructive blending with video
- Optional external RAM/ROM support for custom graphics or fonts
- 5V operation, suitable for compact, cost-effective video overlays
- ESA+T denotes the specific packaging/temperature variant (USB/Tape-and-Reel packaging is common in this line)
Note: Exact font sizes, window counts, and attribute options may vary by revision; consult the datasheet for precise register definitions and capabilities.

Package

Plastic Quad Flat Pack (LQFP) package; the “+T” denotes Tape & Reel packaging.

Pinout

- Pin count: 28 pins (SOP/TSSOP package, e.g., MAX7450ESA+T).
- Function: NTSC/PAL encoder with on-screen display (OSD) overlay. Accepts digital video data, overlays graphics/text via built-in OSD engine, and outputs composite video (CVBS) with a serial (SPI-like) control interface for configuration.

Manufacturer

Manufacturer: Maxim Integrated Products, Inc.
What kind of company: Maxim Integrated is a fabless semiconductor company that designs and markets analog and mixed-signal integrated circuits; it is now part of Analog Devices.

Application

Max7450ESA+T is a stand-alone OSD/overlay generator for video (NTSC/PAL). Applications: automotive (instrument clusters, head-up displays, rear-camera overlays); consumer AV (set-top boxes, DVD/VCR players, game consoles, camcorders); industrial/security video (CCTV, machine-vision overlays); aviation/military displays; digital signage and multimedia kiosks.
