BCM4775X

Product Brief

GNSS Receiver with Integrated Sensor

Hub

Overview

The Broadcom® BCM4775X family of chips is the latest generation of

Broadcom sensor hub microcontrollers with integrated GNSS (Global

Navigation Satellite System). The BCM4775X includes many sensor hub and

GNSS innovations.

The synergistic beneﬁts of combining sensor hub and GNSS chips into one

single chip include low system-level power consumption and a smaller PCB

footprint with fewer BOM components than multiple-chip solutions.

The BCM4775X family includes a dual-processor architecture (ARM

CM4+CM0) that ensures each task is handled in the most power-eﬃcient

manner. The BCM4775X includes a new RF architecture, enabling the

lowest power consumption at any received signal condition.

Key Features

• Integrated multi-frequency GNSS

baseband and RF front end for

simultaneous reception of GPS,

GLONASS, BeiDou (BDS), Galileo

(GAL), and SBAS satellite systems

The BCM4775X achieves system-level performance beneﬁts from tightly

integrating the sensor and GNSS signals. Measurements from sensors such

as accelerometers, gyroscopes, magnetometers, and others are fused with

GNSS measurements to provide a highly accurate, cross-calibrated output

to applications while lowering system power. Cross-calibration is achieved

by using sensor measurements to aid GNSS for small movements and by

using GNSS to calibrate sensor measurements, the latter having inherent

drift that accumulates over time and larger movements.

• Support for position batching,

geofencing, sensor fusion and sensor

navigation

• ARM-based 32-bit Cortex-M4F (CM4)

CPU:

−Single-precision Floating Point Unit

(FPU)

The BCM47755 chip supports two frequencies (L1+L5), and as a result,

achieves lane-level accuracy outdoors and much higher resistance to

multipath and reﬂected signals in urban scenarios, as well as higher

immunity to interference and jamming. The BCM47755 can simultaneously

receive the following signals:

−Memory Protection Unit (MPU)

−1.125 MB internal SRAM (single-cycle

access at full-speed)

−1 MB ROM with bootloader capability

• GPS L1 C/A

• GLONASS L1

• BeiDou (BDS) B1

• QZSS L1

−Single Instruction Multiple Data

(SIMD) and Digital Signal Processing

(DSP) functions

−1.25 Dhrystone MIPS/MHz

−Operating frequency up to 150 MHz

• ARM-based Cortex-M0 (CM0) CPU:

• Galileo (GAL) E1

• GPS L5

−Allows CM4 to sleep by oﬄoading

light processes

• Galileo E5a

• QZSS L5

−32 KB RAM

−Operating frequency of up to 75 MHz
