16-bit microcontroller with 2.0B
CANs more than just cars
C164CI-8EM based microcontroller core C166 type with interrupt response time processing power MIPS MHz. Among highlights one-time programmable memory (OTP) integrated chip with capacity bytes, feature which results significantly shorter transit times. final programming capability serial interface offers users even greater flexibility. C164CI-8EM large data memory bytes RAM. monolithically integrated CAN-2.0B interface used network systems basis standard widely used automotive industrial sectors. versatile 16-bit pulse width modulator with channels also accommodated chip, making C164CI-8EM ideally suited industrial applications. Because only very external components required, large number electrical drives operated convenient costefficient way. power consumption C164CI-8EM optimized with improved power-saving mechanisms. Only those peripheral modules actually required activated others kept sleep mode that power consumption drops mere C164CI-8EM continues operate background. real-time clock ensures that processor always ready spring into action. converter with resolution bits also incorporated. C164CI-8EM encapsulated 80-pin MQFP plastic package. Third-party manufacturers offer extensive range hardware software tools support user during development phase. addition low-cost starter kits, programming hardware emulators also available. C164CI-8EM testing phase final preparations being made serial production. Because increasing price pressure automotive applications safety functions other loads (body control) well need offer even higher performance future, Siemens will shortly introducing C164 derivatives systems such air-conditioning power-assisted steering. C164 follow-on models with flash memory, EEPROMs low-cost ROMs also planned. mid-range automobile available today contains approximately cable well around
