LC87F5WC8AVU-QIP-H

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.

• Flash ROM : 131072 x 8 bits
  Capable 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) V_DD=2.8 to 5.5V
  125ns (8MHz) V_DD=2.5 to 5.5V
  500ns (2MHz) V_DD=2.2 to 5.5V
  Note: Bus cycle time indicates the speed to read ROM.
• Minimum Instruction Cycle Time (tCYC) :
  250ns (12MHz) V_DD=2.8 to 5.5V
  375ns (8MHz) V_DD=2.5 to 5.5V
  1.5s (2MHz) V_DD=2.2 to 5.5V
