LC88F52H0A
CMOS IC
FROM 512K byte, RAM 24K byte on-chip
16-bit 1-chip Microcontroller
http://onsemi.com
Overview
The LC88F52H0A is a 16-bit microcomputer that, centered around an Xstromy16 CPU, integrates on a single chip a
number of hardware features such as 512K-byte flash ROM (onboard programmable), 24K-byte RAM, eight 16-bit
timers, a base timer serving as a time-of-day clock,, a real time clock, two synchronous SIO interfaces with automatic
transmission capability, two single master I2C/synchronous SIO interface, a slave I2C/synchronous SIO interface, four
asynchronous SIO (UART) interfaces, a 16-channel 12-bit resolution AD converter, 8bit resolution DA converter,
four multifrequency 12-bit PWM modules, a watchdog timer, a system clock frequency divider, a 59-source (32
modules) 14-vector interrupt feature, and on-chip debugger feature.

LC88F52H0A
Interrupts (peripheral function)
59 sources (32 modules), 14 vector addresses
1) Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control. Any interrupt requests of
the level equal to or lower than the current interrupt are not accepted.
2) When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the highest level
takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest vector
address takes precedence.
