The SANYO LC87F2832A 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 32K-byte flash ROM (onboard
programmable), 1024-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 (with
automatic block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a UART interface (full
duplex), an 8-bit 11-channel AD converter, two 12-bit PWM channels, a system clock frequency divider, frequency
variable RC oscillation circuit , and a 25-source 10-vector interrupt feature.
Flash ROM
• Capable of on-board-programing with wide range, 3.0 to 5.5V, of voltage source.
• Block-erasable in 128-byte units
• Writable in 2-byte units
• 32768 × 8 bits (LC87F2832A)
• 1024 × 9 bits (LC87F2832A)
Minimum Bus Cycle
• 83.3ns (12MHz)
VDD=3.0 to 5.5V
• 125ns (8MHz)
VDD=2.5 to 5.5V
• 250ns (4MHz)
VDD=2.2 to 5.5V
Note: The bus cycle time here refers to the ROM read speed.
