DESCRIPTION  
Configurable Digital Band-Pass Filter  
Digital Signal Envelope Detect  
On-Chip 8-Bit Microprocessor  
LIN 2.1 Physical Interface and Protocol  
Watchdog Timer  
The PGA450-Q1 is a fully integrated interface device  
for ultrasonic transducers used in automotive park  
distance or object detection applications. It  
incorporates these system blocks: voltage regulators,  
a 12-bit SAR ADC, an 8-bit microcontroller, a digital  
band-pass filter, a DAC, dual NMOS low-side drivers,  
a low-noise amplifier, an oscillator, and a LIN 2.1  
physical interface and protocol for interfacing.  
Four-Wire SPI for Testability / Programming  
8K Bytes OTP  
768 Bytes of FIFO RAM  
The PGA450-Q1 possesses an 8-bit microcontroller  
and OTP memory for program storage for processing  
the echo signal and calculating the distance between  
the transducer and the object. This data is  
transmitted through the LIN 2.1 communication  
protocol. The LIN 2.1 physical layer is slave-only and  
does not implement the LIN wake-up feature. All  
other LIN 2.1 features can be implemented in  
software.  
256 Bytes Scratchpad RAM  
8K Bytes of Development RAM  
32 Bytes of EEPROM for Application
