LC87FBH08A: 8-bit Microcontroller with 8K-byte Flash ROM and 256-byte RAM
The LC87FBH08A is an 8-bit microcontroller 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 8K-byte flash ROM (On-boardprogrammable), 256-byte RAM, an On-chip-debugger (flash versions only), 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), two 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 12-bit/8-bit 11-channel AD converter, a high-speed clock counter, a system clock frequency divider, an internal high-accuracy oscillator, a reference voltage generator circuit, an internal reset and a 20-source 10-vector interrupt feature.
Features- Flash ROM : 8192 x 8 bitsCapable of On-board programming with wide range (2.2 to 5.5V) of voltage source.Block-erasable in 128 byte unitsWritable in 2-byte units
- RAM : 256 x 9 bits
- Minimum Bus Cycle :83.3ns (12MHz at VDD=2.7V to 5.5V, Ta=-40°C to +85°C)100ns (10MHz at VDD=2.2V to 5.5V, Ta=-40°C to +85°C)250ns ( 4MHz at VDD=1.8V to 5.5V, Ta=-40°C to +85°C)Note: The bus cycle time here refers to the ROM read speed.
