Leading the way in the set-top box world

You decide the functionality…

ST has developed complete scalable

solutions targeted for low to high end

set-top box requirements. With our

silicon technology and your system

knowledge we can easily deliver

advanced multi-functional boxes for

all your needs. Starting from the basic

broadcast box, where price is a major

driving force, we have cost optimized

chipsets and two layer printed circuit

board (pcb) layouts. Moving to the

higher end boxes, we can add our

extensive in-house and third party

relationships to add middleware, trick

mode and DVD certified software. For

the whole home concept we can

provide a network approach where

each box can share the content and

functionality of all other boxes in the

network.

wide range of complementary devices

Digital consumer applications – and set-top boxes in particular – aredriving the demand for more flexible, more secure and enhancedperformance non-volatile memories. Benefiting from closerelationships with the world's leading set-top box manufacturers, SToffers a broad range of competitive solutions for the current andemerging generation of set-top boxes

Meeting the set-top box challenge with ST FlashWhen higher densities or advanced performances arerequired, the M58LWxxx family provides the solution. Theproducts are available in different versions, each of themoffering enhanced features. The M58LWxxxC family isalso available with additional security features, which makeit ideal for set-top box applications.

Flash and securityWithout these security features, hackers can change thecontent of Flash memory to get free access to the service.However, once a sector is locked with smart protection, thisis impossible - their only option is to remove and replacethe Flash memory. But the new memory won’t have thesame unique code as the original, so the service providersimply needs to compare the Flash code with the smartcardserial number. If these numbers are inconsistent with itsrecords, service will be denied.

Industry-standard Flash ST’s comprehensive range of Flash products offers densitiesfrom 1 to 64Mb, 3V and 5V single supply, or 3V dual-supply voltage, top and bottom boot block, access timesfrom 55 to 120ns, and in TSOP, SO, PLCC, TFBGApackages.

LightFlash™ familyThis is a dynamic product family with devices from 16 to64Mb, featuring a 3V power supply and 90ns access time,plus a standard Flash command set and pinouts. It is anapplication-oriented product family, focusing on systemperformance optimized for basic code storage.

Serial FlashThey are particularly well suited for small code storage(patches, model-specific codes). They feature high densityand high data-transfer rate, sequential read capability, lowpower consumption and a small low-cost 8-pin package.ST’s portfolio covers 1 to 16Mb, with a 2.7 to 3.6V supplyvoltage.

Serial EEPROMsOffered in a very small package, these are a cost-effectiveand flexible solutions for the storage of system and userparameters.

Used by the major set-top box manufacturers, thesedevices are easily upgradeable to higher densities. ST’scomplete range includes 1Kb to 1Mb products supportingI2C bus (most popular choice), 1 to 256Kb productssupporting SPI bus and 1 to 16Kb products withMICROWIRE® bus, with supply voltages from 1.8 to 5.5V.

ST custom solutions also offer the opportunity tocustomize the interface and associated protocol, the logiccircuitry, the access control and the memory partitioning.

EPROMSA complete range of products from 64Kb to 64Mb,including UV and OTP versions, available in 3V and 5Vversions.

FlexibleROM™ familyA new one-time programmable (OTP) family based on0.15mm process technology. With a portfolio coveringdensities from 16 to 128Mb, it is the ideal solution for set-top boxes, once the code is frozen.

Power supplyMost set-top boxes require up to 5 different voltages. The topology of power supplies whichmeet this requirement are either flyback converters for power in the range from 3 to100W, or forward converters. ST’s wide range of products is dedicated to power supplies which include our smart VIPer family, MOSFETs, line regulators, DC-DCconverters, voltage referencing, Schottky diodes and ultrafast rectifiers which meet with all power supply requirements.

Summary

The hardware reference designs are complemented by the established low level driver set, STAPI. This allowsthird party software houses to port either proprietary middleware application layers or open standard applications such as MHP and MHEG directly on to ST reference platforms. ST has worked with many thirdparties to be able to offer complete solutions while continuously reducing time to market.

Implemented with the most advanced digital silicon process technology available and meeting the need foreven smaller IC geometry, our chipsets’ cost/performance ratio allows the set-top box market to meet its verylow cost requirements for box materials and to rapidly grow in both the operator controlled and retail markets.
