SONY CXD2930BR

CXD2930BR
GPS LSI with Built-in 32-bit RISC CPU
Description
The CXD2930BR is a dedicated LSI for the GPS
(Global Positioning System) satellite-based position
measurement system. This LSI contains a 32-bit
RISC CPU, RAM, UART, timer, etc.
This LSI, used together with an external ROM and
RF LSI (CXA1951AQ), enables the configuration of
a 3-chip system capable of measuring its position
anywhere on the globe.
144 pin LQFP (Plastic)
Features
• 16-channel GPS receiver capable of simultaneously receiving 16 satellites
• Supports DARC system FM multiplexed differential GPS
• All-in-view measurement
• 2-satellite measurement
• Timer supporting GPS time

Battery Backup Mode
The battery backup mode is activated when the power for the GPS receiver is turned off and power-on reset
goes to low level. The timer clock continues to operate even when power-on reset goes low, but all other
clocks are fixed high and the LSI is set to the low power consumption mode. At this time, the RAM data is held
and the registers are initialized.
Battery backup mode is canceled by setting power-on reset to high.

CXD2930BR Startup and Initialization
The CXD2930BR operation is started by setting the reset input signal EXRS (Pin 30) to high level. The timing
should satisfy the conditions noted below.
1. During power-on (power-on reset)
VDD = 3.0 to 3.6V, Topr = –40 to +85°C

The PWRST (Pin 28) signal should rise simultaneously with the power supply. The EXRS (Pin 27) signal
should rise 100ms or more after the power supply and the PWRST signal have risen.
Note that the PWRST signal should be left open during battery backup.
2. Initialization during operation

The internal registers can be initialized during operation by setting the EXRS (Pin 27) signal to low level for
100µs or more.
Keep the PWRST (Pin 28) signal at high level at this time.

CXD2930BR
Description of Application Circuit
See the Application Circuit when using the CXD2930BR to configure a GPS receiver.
Points for caution are as follows.
1. Unused pins
Software processing is performed to prevent undesired current from flowing to unused pins in the circuit
diagram, so leave these pins open.
2. TCXO input
The TCXO frequency is 18.414MHz ± 3ppm. Signals that have not been binary-converted should be input
with an amplitude of 0.8Vp-p or more via a DC filter capacitor (C19 in the circuit diagram). Input binaryconverted signals directly to Pin 7 (TCXO) without passing through C19 or R1 in the circuit diagram.
Make sure the input level at this time satisfies the Electrical Characteristics.
3. IF input
The CXD2930BR interface is 1.023MHz, and does not accept other frequencies. Signals that have not been
binary-converted should be input with an amplitude of 0.8Vp-p or more via a DC filter capacitor (C20). Input
binary-converted signals directly to Pin 18 (IF0) without passing through C20 or R3 in the circuit diagram.
Make sure the input level at this time satisfies the Electrical Characteristics.
4. TXD (SIO output)
The TXD amplitude low level is 0.4V or less, and the high level is VDD – 0.4V (VDD = 3.0 to 3.6V) or more.
When the LSI, etc., connected to TXD operates at 5V and has a CMOS input level, perform 3 to 5V
conversion before inputting the signal.
5. Real-time clock
The current software version uses an external real-time clock. Consult your Sony representative beforehand
when using the internal real-time clock. When using an external real-time clock, connect Pin 13 (CCKI) to
GND.
6. External program ROM
Use a 2M- or 4M-bit external program ROM (IC2) with an access time of 100ns or less and which is capable
of 16-bit read.
