Ordering number : ENA1384B LC87F2J32A CMOS IC FROM 32K byte, RAM 1024 byte on-chip LC87F2J32A Package Dimensions unit : mm (typ) 3163B 9.0 7.0 36 25 24 37 48 13 112 0.5 0.18 0.15 (0.75) SANYO : SQFP48(7X7) Minimum Bus Cycle 83.3ns (12MHz) V =2.7 to 5.5V DD 100ns (10MHz) V =2.2 to 5.5V DD 250ns (4MHz) V =1.8 to 5.5V DD Note: The bus cycle time here refers to the ROM read speed. Minimum Instruction Cycle Time 250ns (12MHz) V =2.7 to 5.5V DD 300ns (10MHz) V =2.2 to 5.5V DD 750ns (4MHz) V =1.8 to 5.5V DD Ports Normal withstand voltage I/O ports Ports I/O direction can be designated in 1-bit units 39 (P0n, P1n, P2n, P30 to P36, P70 to P73, PWM0, PWM1, XT2, CF2) Dedicated oscillator ports/input ports 2 (CF1, XT1) Reset pin 1 (RES) Power pins 6 (V 1 to 3, V 1 to 3) SS DD Timers Timer 0: 16-bit timer/counter with a capture register. Mode 0: 8-bit timer with an 8-bit programmable prescaler (with an 8-bit capture register) 2 channels Mode 1: 8-bit timer with an 8-bit programmable prescaler (with an 8-bit capture register) + 8-bit counter (with an 8-bit capture register) Mode 2: 16-bit timer with an 8-bit programmable prescaler (with a 16-bit capture register) Mode 3: 16-bit counter (with a 16-bit capture register) Timer 1: 16-bit timer/counter that supports PWM/toggle outputs Mode 0: 8-bit timer with an 8-bit prescaler (with toggle outputs) + 8-bit timer/counter with an 8-bit prescaler (with toggle outputs) Mode 1: 8-bit PWM with an 8-bit prescaler 2 channels Mode 2: 16-bit timer/counter with an 8-bit prescaler (with toggle outputs) (toggle outputs also possible from the lower-order 8 bits) Mode 3: 16-bit timer with an 8-bit prescaler (with toggle outputs) (The lower-order 8 bits can be used as PWM.)
