LC87F5WC8A: 8-bit Microcontroller with 128K-byte Flash ROM and 4096-byte RAM
The LC87F5WC8A is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 83.3ns, integrate on a single chip a number of hardware features such as 128K-byte flash ROM (onboard rewritable), 4096byte RAM, Onchip debugging function, 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, two synchronous SIO ports (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO port, two UART ports (full duplex), four 12-bit PWM channels, an 8-bit 15-channel AD converter, a system clock frequency divider, and a 29-source 10-vector interrupt feature.
Features- Flash ROM : 131072 x 8 bitsCapable of on-board-programing with wide range, 2.7 to 5.5V, of voltage source.Block erase in 128 byte units
- RAM : 4096 x 9-bits
- Minimum Bus Cycle Time :
83.3ns (12MHz) VDD=2.8 to 5.5V125ns (8MHz) VDD=2.5 to 5.5V500ns (2MHz) VDD=2.2 to 5.5VNote: Bus cycle time indicates the speed to read ROM.
