LC87F2C64A
CMOS IC
64K-byte FROM and 2048-byte RAM integrated
8-bit 1-chip Microcontroller
Overview
The SANYO LC87F2C64A 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 64K-byte flash ROM (onboard
programmable), 2048-byte RAM, an on-chip debugger, 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 calendar function (RTC), High-speed clock counter, a synchronous SIO interface (with automatic block
transmission/reception capabilities), an asynchronous/synchronous SIO interface, two channels of UART interface (full
duplex), four 12bit-PWMs, a 12/8-bit 16-channel AD converter, a system clock frequency divider, an internal reset
function and a 28-source 10-vector interrupt feature.
Features
Flash ROM
• On-board-programmable with wide range (3.0 to 5.5V) of voltage source
• Block-erasable in 128 byte units
• Writable in 2-byte units
• 65536 × 8 bits
RAM
• 2048 × 9 bits
Minimum Bus Cycle
• 83.3ns (12MHz at VDD=3.0V to 5.5V)
• 250ns (4MHz at VDD=2.4V to 5.5V)
Note: The bus cycle time here refers to the ROM read speed.

LC87F2C64A
Standby Function
• HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation.
(1) Oscillation is not halted automatically.
(2) There are three ways of resetting the HALT mode.
1) Setting the reset pin to the lower level
2) System resetting by watchdog timer
3) Occurrence of an interrupt
• HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
(1) The CF, RC, crystal, and frequency variable RC oscillators automatically stop operation.
(2) There are five ways of resetting the HOLD mode.
1) Setting the reset pin to the lower level
2) System resetting by watchdog timer
3) Setting at least one of the INT0, INT1, INT2, INT3, INT4, INT5 pins to the specified level
4) Having an interrupt source established at port 0
5) Having an interrupt source established in SPI receiving 1-byte (8-bit clock)
• X’'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except the base timer.
(1) The CF, RC, and frequency variable RC oscillators automatically stop operation.
(2) The state of crystal oscillation established when the X’tal HOLD mode is entered is retained.
(3) Power-save mode is available for even lower current consumption.
(4) There are seven ways of resetting the X’tal HOLD mode.
1) Setting the reset pin to the low level
2) System resetting by watchdog timer
3) Setting at least one of the INT0, INT1, INT2, INT3, INT4, INT5 pins to the specified level
4) Having an interrupt source established at port0
5) Having an interrupt source established in the base timer circuit
6) Having an interrupt source established in the RTC
7) Having an interrupt source established in SPI receiving 1-byte (8-bit clock)
On-chip Debugging Function (flash ROM version)
• Supports software debugging with the test device installed on the target board.
Data Security Function (flash ROM version)
• Protects the program data stored in flash memory from unauthorized read or copy.
Note: The data security function does not necessarily provide an absolute data security.
Shipping form
• QFP80 (14×14): Lead-free type
• TQFP80J (12×12): Lead-free type
Development Tools
• On-chip-debugger: TCB87 TypeB + LC87F2C64A
