(Some parts of the serial transfer function stops operation.) 1) Oscillation is not stopped automatically. 2) Canceled by a system reset or occurrence of an interrupt • HOLD mode: Suspends instruction execution and the operation of the peripheral circuits. 1) The CF, RC, X’tal, and multifrequency RC oscillators automatically stop operation. 2) There are three ways of resetting the HOLD mode. (1) Setting the reset pin to the low level (2) Setting at least one of the INT0, INT1, and INT2, pins to the specified level (3) Having an interrupt source established at port 0 • X'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except the base timer and infrared remote controller circuit. 1) The CF, RC, and multifrequency RC oscillators automatically stop operation 2) The state of crystal oscillation established when the X'tal HOLD mode is entered is retained. 3) There are five ways of resetting the X'tal HOLD mode. (1) Setting the reset pin to the low level (2) Setting at least one of the INT0, INT1, and INT2 pins to the specified level (3) Having an interrupt source established at port 0 (4) Having an interrupt source established in the base timer circuit (5) Having an interrupt source established in the infrared remote control receiver circuit On-chip Debugger function • Supports software debugging with the IC mounted on the target board. Package Form • QFP80(14×14): • TQFP80J(12×12): Lead-free type Lead-free type Development Tools • On-chip debugger: TCB87-TypeB + LC87F76C8A Flash ROM Programming Board Package Programming Board QFP80(14×14) W87F71256QF TQFP80J(12×12) W87F71256SQ Same Package and Pin Assignment as Flash ROM Version 1) LC877600 series options can be specified by using flash ROM data. Thus the board used for mass production can be used for debugging and evaluation without modifications. 2) If the program for the mask ROM version is used, the size of the available ROM/RAM spaces is the same as that of the mask ROM version.

Data can be read into any input port even if it is in the output mode. Port Name Option Selected in Units of Option Type Output Type Pull-up Resistor P00 to P07 1 bit 1 CMOS Programmable (Note) 2 N-channel open drain No P10 to P17 1 bit 1 CMOS Programmable 2 N-channel open drain Programmable P30 to P31 1 bit 1 CMOS Programmable 2 N-channel open drain Programmable P70 - No N-channel open drain Programmable P71 to P73 - No CMOS Programmable P80 to P87 - No N-channel open drain No S0/PA0 to S31/PD7 - No CMOS Programmable COM0/PL0 to COM3/PL3 - No Input only No V1/PL4 to V3/PL6 - No Input only No XT1 - No Input only No XT2 - No Output for 32.768kHz crystal oscillator (Nch-open No drain when in general-purpose output mode) Note: Programmable pull-up resistors for port 0 are controlled in 4 bit units (P00 to 03, P04 to 07). 1 Connect the IC as shown below to minimize the noise input to the VDD1 pin. Be sure to electrically short the VSS1, VSS2, and VSS3 pins. Power supply For backup 2 LSI VDD1 VDD2 VDD3 VSS1 VSS2 VSS3 2 The internal memory is sustained by VDD1. If none of VDD2 and VDD3 are backed up, the high level output at the ports are unstable in the HOLD backup mode, allowing through current to flow into the input buffer and thus shortening the backup time. Make sure that the port outputs are held at the low level in the HOLD backup mode. No.A0965-11/25 Datasheet pdf - http://www.DataSheet4U.net/ 11 Page
