8-BIT MICROCONTROLLER
WITH 8KB OTP
AP160
DATA SHEET
October 2001
GENERAL DESCRIPTION
The AP160 is a wide operating voltage, Low power consumption and high performance with AMIC high-density CMOS
technology. All instruction set of AP160 are fully compatible with the standard 8051. The AP160 contains 8K bytes OTP
EPROM, 256 bytes RAM, four 8-bit bi-directional and bit addressable I/O ports, three 16-bit timer/counter and eight interrupt
sources. To reduce power consumption, idle mode and power down mode are provided to implementation. For data
protection, program lock bits can be performed through programming LB1, LB2 and LB3. The AMIC AP160 is a useful and
powerful microcontroller in many control system application.

DESCRIPTIONS
O/I Address Latch Enable is an output pulse for latching the low byte of the address during
accesses to external memory. This pin is also the program pulse input (PROG) during
Programming on-chip OPT EPROM. In normal operation, ALE is emitted at a constant rate of
1/6 the oscillator frequency and may be used for external timing or clocking purposes. Note,
however, that one ALE pulse is skipped during each access to external data memory. If
desired, ALE operation can be disabled by setting bit 0 of SFR location 8EH. With the bit set,
ALE is active only during a MOVX or MOVC instruction. Otherwise, the pin is weakly pulled
high. Setting the ALE-disable bit has no effect if the microcontroller is in external execution
mode.
O Program Store Enable is the read strobe to external program memory. When the AP160 is
executing code from external program memory, PSEN is activated twice each machine cycle,
except that two PSEN activations are skipped during each access to external data memory.
I External Access Enable. EA must be strapped to GND in order to enable the device to fetch
code from external program memory locations starting at 0000H up to FFFFH. Note, however,
that if lock bit 1 is programmed, EA will be internally latched on reset. EA should be strapped to
VCC for internal program executions. This pin also receives the 12-volt programming enable
voltage (VPP) during programming OTP EPROM.
I Input to the inverting oscillator amplifier and input to the internal clock operating circuit.
O Output from the inverting oscillator amplifier.

Programmable Clock Out
A 50% duty cycle clock can be programmed to come out on P1.0, as shown in Figure 5. This pin, besides being a regular
I/O pin, has two alternate functions. It can be programmed to input the external clock for Timer/Counter 2 or to output a 50%
duty cycle clock ranging from 61 HZ to 4MHZ at a 16MHZ operating frequency. To configure the Timer/Counter 2 as a clock
generator, bit C/T2 (T2CON.1) must be cleared and bit T2OE (T2MOD.1) must be set. Bit Tr2 (T2CON.2) starts and stops
the timer. The clock-out frequency depends on the oscillator frequency and the reload value of Timer 2 capture registers
(RCAP2H, RCAP2L), as shown in the following equation.
Oscillator Frequency
Clock − Out Frequency =
4 × [65535 − (RCAP2H , RCAP2L)]
In the clock-out mode, Timer 2 roll-overs will not generate an interrupt. This behavior is similar to when Timer 2 is used as a
baud-rate generator. It is possible to use Timer 2 as a baud-rate generator and a clock generator simultaneously. Note,
however, that the baud-rate and clock-out frequencies cannot be determined independently from one another since they
both use RCAP2H and RCAP2L.
