The TLE983x is a single chip solution that integrates a high performance 8-bit microcontroller derived from the established XC800 family with application specific power drivers, control and communication modules in an automotive qualified new Smart-Power Technology. The TLE983x family concept offers scalability in terms of Flash memory sizes ranging from 36kB to 64kB with pin-compatible devices. The TLE983x family was specifically designed to fit to a wide range of LIN-slave applications where a small package form factor and a minimum number of external components is essential. TLE983x主要特性: • High performance XC800 core – compatible to standard 8051 core – up to 40 MHz clock frequency – two clocks per machine cycle architecture – two data pointers • On-chip memory – 20, 32, 44 or 60 kByte + 4 kByte Flash for program code and data (4 kByte EEPROM emulation built-in) – 512 Byte One Time Programmable Memory (OTP) – 512 Byte 100 Time Programmable Memory (100TP) – 256 Byte RAM – 3 kByte XRAM – BootROM for startup firmware and Flash routines • Core logic supply at 1.5 V • On-chip OSC and PLL for clock generation – Loss of clock detection with fail safe mode for LSS, HSS and LIN • Watchdog timer (WDT) with programmable window feature for refresh operation and warning prior to overflow • General-purpose I/O Port (GPIO) with wake-up capability • Multiplication/division unit (MDU) for arithmetic calculation • Software libraries to support floating point and MDU calculations • Five 16-Bit timers - Timer 0, Timer 1, Timer 2, Timer 21 and Timer 3 • Capture/compare unit for PWM signal generation (CCU6) and Hall Sensor measurement with Timer 12 and Timer 13 • Full duplex serial interface (UART) with LIN support • Synchronous serial channel (SSC) • On-chip debug support via 2-wire Device Access Port (DAP) • LIN Bootstrap loader (LIN BSL) • LIN transceiver compliant to LIN 1.3, LIN 2.0 and LIN 2.1 • 2 x Low Side Switches with clamping capability incl.
