NCN49599 Product Preview Power Line Communication Modem The NCN49599 is a powerful spread frequency shift keying (SFSK) communication systemonchip (SoC) designed for www.onsemi.com communication in hostile environments. It combines a low power ARM Cortex M0 processor with a high precision analogue front end and a robust line driver. Based on 4800 baud SFSK dualchannel technology, it offers an ideal compromise between speed and robustness. It is functionally compatible with the NCN49597 and NCS5651 1 56 chip set, offering frequencies to cover all CENELEC bands for use in QFN56 8x8, 0.5P applications such as emetering, home automation and street lighting. CASE 485CN The NCN49599 benefits for more than 10 years of field experience in emetering and delivers innovative features such as a smart synchronization and inband statistics. MARKING DIAGRAMS Fully reprogrammable, the modem firmware can be updated in the 56 field. Multiple royaltyfree firmware options are available from 1 ON Semiconductor refer to the separate datasheets for details. The ARM ON configurable GPIOs allow connecting peripherals such as LCDs or NCN49599 metering ICs. 0C599001 AWLYYWWG Features e 3 Power Line Communication (PLC) Modem for 50 Hz, 60 Hz and DC Mains A = Assembly Location Embedded Highly Linear 2stage Power Amplifier with Current WL = Wafer Lot Traceability YYWW = Date Code Limitation, Thermal Protection, Enable/Shutdown Control, G = Green Designator Railtorail Drop of only 1 V at I = 1.5 A out Embedded ARM Cortex M0 Processor 8 Generalpurpose IOs Controllable by Software ORDERING INFORMATION See detailed ordering and shipping information in the package Embedded 32 kB RAM Embedded 2 kB ROM dimensions section on page 33 of this data sheet.
