MG87FE/L52
1.0 General Description
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.
2.0 Features
z 80C51 Central Processing Unit
z 8KB On-Chip program memory for program ROM, ISP ROM & IAP zone.
z ISP capability; optional 0.5K/1KB/1.5K~3.5KB ISP memory shared with 8KB flash memory.
z IAP capability; program controlled IAP memory size shared with 8KB flash memory.
z On-Chip 256 bytes scratch-pad RAM. Also, the MCU can address up to 64K bytes external
memory.
z MOVC-disabling, encrypting, and locking flash memory realize security mechanism.
z Three 16-bits timer/counter, Timer2 is an up/down counter with programmable clock output
on P1.0
z Eight sources, four-level-priority interrupt capability
z Enhanced UART, provides frame-error detection and hardware address-recognition
z Dual DPTR for fast-accessing of data memory
z 15 bits Watch-Dog-Timer with 8-bits pre-scaler, one-time enabled
z Low EMI: inhibits ALE emission
z 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.
z I/O port: 32+4 I/O ports :
- PDIP-40 (MG87FE/L52AE or MG87FE/L52GE) has 32 I/O ports;

37 I/O Port0 is an open-drain, bi-directional
36 IO port. When 1s are written to Port0,
35 they become high-impedance inputs.
Port0 is also multiplexed with low-order
34
address or data bus during accesses
33 to external program and data memory.

40 I/O Port 1 is an 8-bit bidirectional I/O port
41 with internal pull-ups and can be used
42 as inputs. Port 1 pins that have 1s
written to them are pulled high by the
43
internal pull-ups and can be used as
44 inputs. As inputs, port 1 pins that are
1 externally pulled low will source current
2 because of the internal pull-ups.

P1.0 is also used as one of event
sources for timer2, or output carrier of
timer2, alias T2.
P1.1 is also used as one of
interrupt-controlling sources for timer2,
alias T2EX.

18 I/O Port 2 is an 8-bit bidirectional I/O port
19 with internal pull-ups and can be used
20 as inputs. Port 2 pins that have 1s
written to them are pulled high by the
21
internal pull-ups and can be used as
22 inputs. As inputs, port 2 pins that are
23 externally pulled low will source current
24 because of the internal pull-ups.

Except being as GPIO, Port2 emits the
high-order address bytes during
accessing to external program and
data memory.
