LC87F7932B: 8-bit LCD Driver Microcontroller with 32K-byte Flash ROM and 2048-byte RAM
The LC87F7932B is an 8-bit microcomputer that, centered around a CPU running at a minimum bus cycle time of 250 ns, integrates a number of hardware features such as 32K-byte flash ROM (on-board programmable), 2048-byte RAM, an on-chip debugger, an LCD controller/driver, sophisticated 16-bit timer/counter (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 real time clock function (RTC), a synchronous SIO interface (with automatic block transmission/reception capabilities), an asynchronous/synchronous SIO interface, a full duplex UART interface, a 12-bit/8-bit 7-channel A-D converter, a high speed clock counter, a system clock frequency divider, a power-on reset function and a 21 source, 10 vector interrupt feature.
特性- Flash ROM : 32768 x 8 bitsCapable of onboard programming with wide 3.0 to 5.5 V voltage sourceBlock erasable in 128 byte units
- RAM : 2048 x 9 bits
- Minimum bus cycle time is 250 ns (4.0 MHz) at VDD = 2.4 to 3.6 V
- Minimum instruction cycle time is 750 ns (4 MHz) at VDD = 2.4 to 3.6 V
