• Manufacturer Part Number: BCM4760
• Description: Personal Navigation System-on-chip
• Manufacturer: Broadcom Corp.

The BCM4760 System-on-a-Chip (SoC) combines a high-performance
GPS receiver and baseband, an ARM11™ 500 MHz processor and
companion vector floating point unit, an OpenGL ES 1.1/OpenVG 1.0
compliant graphics processor unit, and advanced analog technology to
deliver the most highly integrated applications processor ever created for
the personal navigation market.
The BCM4760’s high level of integration allows designers to reduce the
cost and complexity of PCB design by eliminating external components
such as audio codecs, touchscreen controllers, and LNAs. Captured in a
small 13 × 13 mm package and manufactured using Broadcom’s low-
power 65 nm process, the BCM4760 was expressly designed for
personal navigation devices (PNDs) and other low-power consumer
electronics products.
The BCM4760 enables system manufacturers to create a platform that
meets the needs of the entry-, mid-, and high-level GPS PND segments.
For the entry market, where low system cost is a primary focus, the
BCM4760 provides the functionality needed to create optimized
solutions. A USB2.0 OTG high-speed controller with integrated
transceiver, 4- or 5-wire touch controller, and audio mixer/DAC simplify
the design and help shrink the PCB footprint while keeping the total bill-
of-material cost to a minimum.
For midlevel PNDs, the BCM4760 has ample processing power for rapid
display of the 3D city maps and 3D landmarks. With the high
performance 3-processor architecture (ARM11, FPU, and GPU),
multiple high-speed serial interfaces, dual Microphone ADC with PGA,
and a 4-channel general-purpose ADC to connect to dead reckoning
sensors, the BCM4760 can easily support a wide range of midlevel

features. Connectivity technologies such as Broadcom’s Bluetooth
WLAN chipsets can be supported by connecting them directly to the
BCM4760 platform. Other features such as hands-free speakerphone,
photo viewing, and music playback are also supported.
For the high-level PND, the BCM4760 supports a direct connection to
Broadcom’s VideoCore
III coprocessor enables high definition video playback or recording,
graphics acceleration, image signal processing (ISP), and more.
The BCM4760 is the first SoC solution to feature a fully integrated, high-
performance GPS RF and baseband solution. The low-noise GPS RF
section features an on-chip LNA, a highly linear mixer/IF gain section,
and 4-bit ADC. The 24-channel GPS baseband features Broadcom’s
patented massive parallel correlation architecture that delivers high
sensitivity and fast time-to-first-fix (TTFF) performance.
Application developers can take advantage of the hardware-based
graphics processing unit to create engaging 2D/3D applications while
including the latest nuances in 3D mapping. Anti-aliasing hardware and
transparency overlaying enrich the look and feel of vector graphics and
also improve overall display performance.
The BCM4760’s advanced power management techniques such as
voltage and frequency scaling, power islands, and optimized power
domains, the BCM4760 puts “portable” back into personal navigation. In
addition, Broadcom offers a companion power management unit that
performs battery and power supply management functions. Using the
two devices together can help achieve greater system power savings.
