8 / 89 page  TDC-GP30 Vol. 1 DB_GP30Y_Vol1_en.docx V0.0 www.acam.de 1-3 1 Overview TDC-GP30 is the next generation in acam’s development for ultrasonic flow converters. The objectives of the TDC-GP30 development are as follows: Easy-to-adapt two-chip solution for ultrasonic heat and water meters (GP30 + simple µP) Single-chip solution for many industrial applications or pure flow meter parts All flow and temperature calculations are done by GP30 External µP needed only for interfaces (e.g. LCD, wireless, etc.) and other general-purpose tasks Integrated standard pulse interface enables one-to-one replacement of mechanical meters by GP30 based single-chip heat and water meters – customer uP and software remains unchanged. All in all, the TDC-GP30 is the next step in ultrasonic flow metering. It drastically simplifies the design of ultrasonic heat and water meters and is the necessary step for compact energy-saving ultrasonic water meters. The ultra-low-current capabilities allow the use of standard 2/3 AA or AA lithium thionyl chloride batteries at 6-8 Hz measuring frequency even in the water meter version. The TDC-GP30 is a system-on-chip approach that allows you to perform all measurement tasks in one IC. 1.1 Key Features High performance + ultra-low power 32-Bit CPU with 128 * 32 NVRAM (non-volatile RAM) for user firmware parameter & data 4k * 8 NVRAM (non-volatile RAM) for user firmware program code 4k * 8 ROM for system task code and special flow library code Capability of MID-compliant flow & temperature calculation, GP30-supported Flexible interfaces, SPI, UART, pulse (flow only) Advanced high-precision analog part Transducers can be connected directly to GP30, no external components required Amplitude measurements of receiving signal for secure bubble, aging and empty spool piece detection Up to 31 multi-hits for flow measurement yield the highest accuracy High update rates with very low power consumption of for example 6 µA at 8 Hz, including flow and temperature calculations, measure rate adopted to the flow Very low space and component requirements |
