Debug is made simple by JTAG support. Standby Mode: 35 mA (MAX.) Sleep Mode: 5.5 mA (MAX.) This high level of integration lowers overall system Stop Mode 2: 18 A costs, reduces development cycle time and acceler- ates product introduction. The LH79520s fully static Watchdog Timer design, power management unit, low voltage operation Vectored Interrupt Controller (1.8 V Core, 3.3 V I/O), on-chip PLL, fast interrupt 16 Standard and 16 Vectored IRQ Interrupts response time, on-chip cache and SRAM, powerful Hardware Interrupt Priority instruction set, and low power RISC core provide high Software Interrupts performance. FIQ Fast Interrupts To build an advanced portable device, advanced pro- cessing capability is required. This capability must come Three UARTs with increased performance in the display system and 16-byte FIFOs for Rx and Tx peripherals, and yet demand less power from batteries. IrDA SIR Support The LH79520 is an integrated solution to fit these needs.
