4 / 21 page LC87F7032A No.A0653-4/21 Subroutine Stack Levels • 512 levels maximum (the stack is allocated in RAM) High-speed Multiplication/Division Instructions • 16-bits × 8-bits (5 tCYC execution time) • 24-bits × 16-bits (12 tCYC execution time) • 16-bits ÷ 8-bits (8 tCYC execution time) • 24-bits ÷ 16-bits (12 tCYC execution time) Oscillation Circuits • On-chip RC oscillation for system clock use. • CF oscillation (4MHz) for system clock use. (Rf built in, Rd external) • Crystal oscillation (32.768kHz) low speed system clock use. (Rf built in, Rd external) • On-chip frequency variable RC oscillation circuit for system clock use. System Clock Divider Function • Low power consumption operation is available • Minimum instruction cycle time (750ns, 1.5µs, 3.0µs, 6.0µs, 12µs, 24µs, 48µs, 96µs, 192µs can be switched by program (when using 4MHz main clock) Standby Function • HALT mode: HALT mode is used to reduce power consumption. During the HALT mode, program execution is stopped but peripheral circuits keep operating (some parts of serial transfer operation stop.) 1) Oscillation circuits are not stopped automatically. 2) Released by the system reset or interrupts. • HOLD mode HOLD mode is used to reduce power consumption. Program execution and peripheral circuits are stopped. 1) CF, RC and crystal oscillation circuits stop automatically. 2) Released by any of the following conditions. (1) Low level input to the reset pin (2) Specified level input to one of INT0, INT1, INT2. (3) Port 0 interrupt • X'tal HOLD mode X’tal HOLD mode is used to reduce power consumption. Program execution is stopped. All peripheral circuits except the base timer are stopped. 1) CF and RC oscillation circuits stop automatically. 2) Crystal oscillator operation is kept in its state at HOLD mode inception. 3) Released by any of the following conditions (1) Low level input to the reset pin (2) Specified level input to one of INT0, INT1, INT2. (3) Port 0 interrupt (4) Base-timer interrupt ROM Correct Function • ROM correct program is executed by checking the program counter. • ROM correct program area: 128byte On-chip Debugger Function • Software debug is available on the target board. Package Form • ΤQFP64J(7×7) :Lead-free type • QIP64E(14×14) :Lead-free type Development Tool • On-chip Debugger: TCB87 TypeB+LC87F7032A |
