2 / 10 page TMPN3120FE3MG 2 2005-11-29 I/O functions • Eleven programmable I/O pins • Two programmable 16-bit timers and counters built in • More than thirty different types of I/O functions to handle a wide range of input and output • ROM firmware image containing preprogrammed I/O drivers, greatly simplifying application programs Network functions • Two CPUs for communication protocol processing built in The communications and application CPUs execute in parallel. • Equipped with a built-in LonTalk protocol supporting all seven levels of the ISO OSI reference model • The ROM firmware image contains a complete network operating system, greatly simplifying application programs. • Built-in twisted-pair wire transceiver • Equipped with communications modes and communication speeds to support various types of external transceivers • Communication port transceiver modes and logical addresses are stored within the EEPROM. Can be amended via the network. Other functions • Application programs are also stored within the EEPROM. Can be updated by downloading over the network. • Built-in watchdog timer • Each chip has a unique ID number. Effective during the logical installation of networks • Low electrical consumption mode supported through a sleep mode • Reset time Prolongs the power-on reset time for at least 50 ms and keeps the operation stable during that time. • High-impedance communication port (CP0 to CP3) when powered down The communication port pins (CP0 to CP3) attain high impedance when the Neuron Chip is powered down. This feature eliminates the need for an external relay. • Built-in low-voltage detection circuit Prevents incorrect operations and writing errors in the EEPROM during drops in power voltage. An external LVD must be used to assert reset at a power supply voltage below 4.5 V if the Neuron Chip is operated at 20 MHz. • The package is SOP32-P-525-1.27 (lead-free type). |
