| | | | | ◊ Đặc điểm chính: | | | MG87FE/L52 is a single-chip 8 bits microcontroller with the instruction sets fully compatible
with industrial-standard 80C51 series microcontroller. 8K bytes flash memory and 256 bytes
RAM has been embedded to provide wide field application. In-System-Programming and
In-Application-Programming allow the users to download new code or data while the
microcontroller sits in the application. This device executes one machine cycle in 6 clock or 12
clock cycles. MG87FE/L52 has four 8-bit I/O ports, one 4-bit I/O ports, three 16-bit
timer/counters, an eight-source, four-priority-level interrupt structure, an enhanced UART,
on-chip crystal oscillator.
Excellent flash-endurance, flash-retention, and code-protecting security make MG87FE/L52 as
an excellent micro-controller. |

Features
·
80C51 Central Processing Unit
·
8KB On-Chip program memory for program ROM, ISP
ROM & IAP zone.
·
ISP capability; optional 0.5K/1KB/1.5K~3.5KB ISP
memory shared with 8KB flash memory.
·
IAP capability; program controlled IAP memory
size shared with 8KB flash memory.
·
On-Chip 256 bytes scratch-pad RAM. Also, the MCU
can address up to 64K bytes external memory.
·
MOVC-disabling, encrypting, and locking flash
memory realize security mechanism.
·
Three 16-bits timer/counter, Timer2 is an
up/down counter with programmable clock output on P1.0
·
Eight sources, four-level-priority interrupt
capability
·
Enhanced UART, provides frame-error detection
and hardware address-recognition z Dual DPTR for fast-accessing of data memory
·
15 bits Watch-Dog-Timer with 8-bits pre-scaler,
one-time enabled
·
Low EMI: inhibits ALE emission
·
Power control: Idle mode and Power-Down mode;
Power-Down can be woken-up by P3.2/P3.3/P4.2/P4.3, Idle mode could be woken up
by all interrupt sources.
