PIC16C57T-10/SS - 8-Bit 10MHz 3KB OTP MCU 28-SSOP | Microchip
MPN: PIC16C57T-10/SS ✓ فعالPIC16C57T-10/SS جائزہ
A microcontroller (MCU) is a single-chip computer that contains a CPU, program memory, data memory, and I/O peripherals. Within the broader taxonomy, the PIC16C57T-10/SS is a Harvard-architecture 8-bit RISC microcontroller in the legacy PIC16C5X base-line family, which sits under the umbrella of embedded controllers and semiconductor ICs. The 'T' suffix denotes tape-and-reel packaging for high-volume SMT assembly, while '/SS' specifies the 28-pin SSOP (5.30 mm body width) footprint.
Key features include a 10 MHz external oscillator, internal watchdog timer, power-on reset, brown-out detection, and an 8-bit timer/counter with programmable prescaler. The device consumes only 2 mA typical at 5 V / 10 MHz and supports four oscillator modes (RC, LP, XT, HS) to trade off power versus clock accuracy. The 20 I/O pins can directly sink/source up to 25 mA per pin, enabling direct LED drive and eliminating external driver buffers in many cost-sensitive designs.
Architecturally, the PIC16C57T-10/SS uses a 12-bit instruction word with separate program and data buses, a 2-stage pipeline, and a 33 single-word instruction set. The OTP program memory allows one-time field programming for low-NRE prototypes and short production runs; for high-volume runs, Microchip offers mask-ROM (-10/SS with no 'T') equivalents. Compared to flash-based successors such as the PIC16F57, the OTP die provides lower cost at the expense of non-erasable code storage.
Typical applications include appliance control, security-system keypads, HVAC fan controllers, battery chargers, simple sensor interfaces, and white-goods user-interface boards. Its wide operating temperature range and EPROM-based reliability make it especially suited to industrial-grade equipment where long-term firmware stability is required. The 28-SSOP package balances compactness with hand-solder-friendly lead pitch for low-volume production.
When designing with this part, allocate the I/O budget early - 20 pins must cover all keypad scanning, LED driving, and sensor I/O. Because OTP memory cannot be updated in the field, design the firmware revision flow to use windowed EPROM prototypes (PIC16C57-10/P in CERDIP) before committing to OTP production. The 'T' suffix indicates tape-and-reel only, not a different temperature grade; the standard part operates over 0°C to +70°C commercial range.

عام استعمالات
PIC16C57T-10/SS کے لیے موزوں ہے 6 ایپلیکیشنs: Appliance Control Boards, Security System Keypads, HVAC Fan and Blower Controllers, Battery Charger Control, White-Goods User Interface Boards, Simple Sensor Interface Modules.
Appliance Control Boards
The PIC16C57T-10/SS is well suited to appliance control boards such as washing machines, dishwashers, and microwave ovens. Its 20 I/O pins at 25 mA sink/source directly drive relay coils, indicator LEDs, and seven-segment displays without external driver buffers, reducing BOM cost. The 3 KB OTP memory holds typical appliance firmware including keypad scanning, timer logic, and safety interlocks. Operates from a single 5 V rail commonly available after rectification from the AC mains, simplifying the power supply design. The wide 4.5 V to 5.5 V tolerance accommodates the droop seen during relay switching transients.

Security System Keypads
Security keypads and access-control panels use the PIC16C57T-10/SS to scan 4x4 or 3x4 matrix keypads, drive piezo buzzers, and control LED status indicators. The 20 I/O count covers 8 keypad rows/columns plus 4 zone-status LEDs and 2 relay outputs for door strikes. The 72-byte RAM is sufficient to debounce keystrokes and store entry-code buffers. The hardware watchdog timer resets the MCU on firmware lockup, a critical safety feature for unattended security equipment. The 28-SSOP package fits inside slim wall-mount keypad housings.

HVAC Fan and Blower Controllers
HVAC fan-speed and blower-motor controllers benefit from the PIC16C57T-10/SS's 10 MIPS instruction rate and 8-bit timer with programmable prescaler. The MCU generates PWM or triac phase-angle control signals to regulate AC motor speed based on thermistor inputs. Its 25 mA I/O drive directly interfaces with optoisolators and triac gate drivers, eliminating interface logic. The OTP memory locks the firmware revision permanently, an advantage for UL-listed equipment where certified firmware must not be field-modified. The 0C to +70C operating range handles conditioned-air equipment closets.

Battery Charger Control
The PIC16C57T-10/SS implements closed-loop charge control for lead-acid, NiCd, and NiMH battery chargers. The 10-bit-equivalent measurement resolution (using internal ADC-less ratiometric techniques via comparator inputs) is sufficient for voltage and current regulation. The watchdog timer prevents charger lockup that could damage batteries. The 5 V operating range is compatible with linear regulators downstream of a transformer-rectified supply. I/O pins directly drive status LEDs and relay-based charge-mode switching.

White-Goods User Interface Boards
White-goods user-interface boards - the display and control PCB behind the front panel of refrigerators, ovens, and washing machines - typically use the PIC16C57T-10/SS. The 28-SSOP package is hand-solder-friendly for low-volume assembly. The 20 I/O pins drive multiplexed 7-segment or 14-segment displays and scan capacitive or resistive touch keypads. Low active current of 2 mA at 5 V/10 MHz means the standby power budget is minimal. The OTP memory locks the user-facing firmware to prevent accidental field changes.

Simple Sensor Interface Modules
Low-cost sensor interface modules - including thermistor readers, photodiode amplifiers, and PIR motion detector boards - use the PIC16C57T-10/SS for signal conditioning and digital output. The MCU reads analog signals via ratiometric techniques using its digital I/O as a poor-man's ADC, then drives a relay or UART-style output. The 3 KB OTP holds linearization tables and threshold logic. Industrial 0C to +70C operation handles indoor environmental sensors. Hardware watchdog ensures unattended sensor modules recover from electrical noise events.

ڈیزائن نوٹس
The PIC16C57T-10/SS requires a stable 4.5 V to 5.5 V supply. Place a 100 nF decoupling capacitor within 5 mm of each VDD pin (pins 14 and 28) and a bulk 10 uF tantalum or aluminum electrolytic at the board's power-entry point. For switching-relay loads sharing the 5 V rail, add a 100 uF reservoir capacitor to absorb inrush transients that can momentarily pull VDD below the brown-out threshold.
Keep the oscillator traces (OSC1/OSC2, pins 16/15) short - under 10 mm if possible - and surround them with a ground pour to minimize EMI pickup. For crystal mode, place load capacitors (typically 15-33 pF) within 2 mm of the OSC pins. Route MCLR (pin 4) away from high-current switching traces to avoid spurious resets.
PIC16C57T-10/SS OTP memory cannot be reprogrammed - one programming cycle per device. Use windowed CERDIP prototypes (PIC16C57-10/P) for firmware development, then commit the final firmware to OTP production parts. Do not confuse the 'T' suffix (tape & reel packaging) with a temperature grade; the standard part is 0C to +70C commercial range. For industrial -40C to +85C operation, specify the 'I' suffix (e.g., PIC16C57T-10I/SS).
The PIC16C57T-10/SS I/O pins have TTL-level thresholds when configured as inputs (VIH >= 2.0 V, VIL <= 0.8 V at VDD = 5 V). For CMOS-level inputs from 3.3 V logic, use a level translator or pull-up resistors to VDD. Output drive strength is rated 25 mA sink/source per pin, but total package dissipation should not exceed 800 mW across all I/O simultaneously.
