LC87F2W48A: 8-bit Microcontroller with 50K-byte Flash ROM and 1536-byte RAM
The LC87F2W48A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 83.3ns, integrates on a single chip a number of hardware features such as 50K-byte flash ROM (On-boardprogrammable), 1536-byte RAM, an On-chip-debugger, sophisticated 16-bit timers/counters (may be divided into 8-bit timers), a 16-bit timer/counter (may be divided into 8-bit timers/counters or 8-bit PWMs), four 8-bit timers with a prescaler, a base timer serving as a time-of-day clock, a high-speed clock counter, a synchronous SIO interface, an asynchronous/synchronous SIO interface, a UART interface (full duplex), two 12-bit PWM channels, a 14-channel AD converter with 12-/8-bit resolution selector, a system clock frequency divider, an infrared remote controller receiver circuit, and a 24-source 10-vector interrupt feature.
Features- Flash ROM : 51200 x 8 bitsCapable of on-board-programming with wide range, 2.7 to 5.5V, of voltage source.Block-erasable in 128 byte unitsWritable in 2-byte units
- RAM : 1536 x 9 bits
- Minimum Bus Cycle : 83.3ns (12MHz) VDD=2.7V to 5.5VNote : The bus cycle time here refers to the ROM read speed.
- Minimum instruction cycle time :250ns (12MHz) VDD=2.7 to 5.5V
